Accepted Minisymposia

  Special Symposium
MS 1 Symposium in honor of Prof. Zdenek P. Bazant on the occasion of his 80th birthday (by invitation only)

Huajian Gao - Brown University
Yonggang Huang - Northwestern University

This symposium is aimed to honor Prof. Zdenek P. Bazant’s scientific accomplishments on the occasion of his 80th birthday. The proposed symposium will bring together leading scientists in the research fields described below to discuss the frontier research issues and directions. The invited speakers will include some of the close friends, colleagues, as well as former and current students and postdocs of Prof. Bazant.
During the last few decades, Prof. Bazant has been leading several important fields of solid and structural mechanics, materials research in concrete and composites, and structural engineering research. He has made important contributions to fundamental theories in fracture, failure and stability of engineering structures, as well as practical applications of these theories in engineering practice. He is the world’s foremost authority and leader on the size effect and scaling in the failure behaviors of quasi-brittle load- bearing structures, especially concrete, sea ice and composites. His work laid the foundation to the understanding of scaling laws that relate material failure behaviors at all scales and sizes. One of his ground breaking contributions was to show that quasi-brittle materials generally exhibit a transition from a Gaussian distribution of failure probability at small specimen sizes to a Weibull type distribution at large size. His theory also allowed the treatment of the “tails” of these distributions using extreme value statistics, which plays a critical role in predicting the structural safety and lifetime of practical engineering structures. In addition to his original research papers, Zdenek has produced a number of books and monographs that have all made great impact to the field. His book on “Scaling of Structural Strength” integrates his original contributions to the size effect and fracture scaling of quasi-brittle materials with many experimental validations, thereby establishing a theoretical basis for relating laboratory scale experiments to practical design of large scale engineering structures. His recent work has included timely engineering topics such as fracking (hydraulic fracturing) of shale, dynamic overstress in fracturing of concrete at high strain rates, size effect and probability distribution of fatigue crack growth and residual strength.

"Computational biomechanics has become an essential component for patient-specific diagnostics and better understanding of physiological and pathological conditions in the human body. Development of predictive and reliable biomechanical models has been greatly facilitated by recent advances in medical imaging modalities and image segmentation techniques. However, there still remain open questions about tackling the immanent complexity of physiological processes and multiscale linking of mechanics across cellular, tissue, and organ levels, which requires interdisciplinary thinking, sophisticated modeling, and advanced numerical methods. Also, the consideration of continuum, solid and fluid mechanics aspects and their interactions across multiple length and temporal scales call for innovative simulation technologies that go beyond standard numerical analysis paradigms. This mini-symposium therefore aims at bringing together researchers from the computational biomechanics community to discuss latest achievements in the development of innovative and advanced numerical methods applied to biological tissues and improved treatments for human body diseases.

"Biological systems exhibit features ranging from nano to macroscale in a hierarchical fashion, which calls for multi-scale modeling and experimental techniques that need to overcome long-standing challenges in accurately capturing the physical, chemical and structural complexities transcending length and time-scales. From another aspect, it is also a long-standing challenge to design engineering materials and structures inspired from biological systems. Recent years have witnessed a wave of renewed interest in designing bioinspired materials and structures especially accompanied with the rapid development of modern fabrication technology, such as nanofabrication and 3D printing. For example, a number of novel top-down or bottom-up fabrication approaches have been developed to tailor materials into bioinspired structures that enable unprecedented properties such as ultra-lightweight, ultra-tough, ultra-strong and ultra-stretchable. This symposium attempts to provide a forum that brings together mechanicians, experimentalists and materials researchers who investigate the mechanical behavior of biological materials with the aim to understand the novel mechanics of biosystems and stipulate designs toward effective biomimicry and bioinspiration. Topics will cover various aspects of mechanics, micro and nanostructures, synthesis and processing of materials and structures inspired by biology including but not limited to following themes:

MS 15 Mechanobiology of Soft and Hard Biological Tissues

Stefan Scheiner - Vienna University of Technology, Austria
Claire Morin - Ecole des Mines de Saint-Etienne, France

Biological tissues usually exhibit complex, often non-linear, and time-dependent mechanical behaviors. These features can be related to the highly heterogeneous and complex organization of the tissue microstructure, as well as to strong couplings that exist in such tissues between the (poro-) mechanical environment and biological as well as chemical processes, with the latter potentially implying changes of the tissue microstructure over time. A wealth of experimental, theoretical, and numerical methods exists for the mechanobiological characterization of the different classes of (soft and hard) tissues. Considering that several of the underlying processes exhibit significant similarities between the different tissues, the goal of this mini-symposium is the cross-fertilization of the usually separated scientific communities studying these processes and methodologies either on soft or hard tissues. Contributions dealing with theoretical, computational, as well as experimental research on the mechanobiology of soft and hard tissues are welcome, including (but not limited to) the following topics, many of which involving or even originating from classical engineering mechanics approaches: biomechanics; poromechanical problems in biological materials; experimental investigation of biological materials; modeling and simulation of mechanical properties of biological materials; cellular sensing/transduction of mechanical loading; soft and hard tissue remodeling, emphasizing on regulatory mechanisms, and related diseases; tissue mineralization/calcification, and related diseases; and multiscale modeling strategies.

In recent years topics such as robustness, resilience, sustainability, life-cycle assessment have shifted into the focus of engineering societies. Many concepts have been developed. Yet, accurate and physically based prediction models and modeling concepts for the time dependent behavior and deterioration of concrete, which are quintessential inputs, are still scarce.

Further topics of interest include coupled problems such as cracking damage and permeability, as well as transport processes in ageing and deteriorating concrete structures.

MS 33 The mechanical failure of hard/soft materials: from yogurt to cement


"Concrete, a prominent example of a hard disordered material, is widely produced more than any other synthetic material on Earth. There is no other material that can replace concrete to meet our societies’ needs for housing and infrastructure by the unique property of cement transforming from liquid to stone. Nevertheless concrete faces an uncertain future, due to a non-negligible ecological footprint that amounts to 5-10% of the worldwide CO2 production. However, concrete has the potential to contribute to a sustainable development encompassing economic growth and social progress upon minimizing its ecological footprint. The recent Fukushima and Macondo disasters highlight the lack of materials technology and the need of renewing engineering practices from science-based principles.
Today the advancement of fundamental knowledge on materials is all about developing a predictive bottom-up approach from the atomic level to micro-texture and macroscopic engineering properties. The first outcome of such an approach for cement was a realistic atomistic model of cement hydrates. Its recent upscaling to a realistic microstructure opens unprecedented possibilities and constitutes the starting point for modeling fracture, creep and aging of cement in the context of durability that is the core of the present symposium. This shift of paradigm based on a bottom-up approach can be applied to and tested for other important multiscale materials: soils and sediments, ceramics, solid nuclear fuels, geo-materials.
Soft solids, like hydrogels and elastomers share common features with stiffer and more rigid materials like cement or asphalt, including delayed failure under constant external stress, crack propagation or work-hardening. Indeed, the response of such soft materials is often well captured by empirical laws observed in a wide range of hard solid (e.g Andrade power-law creep response, Basquin's law of fatigue, the Monkman-Grant relationship and Bailey's durability criterion). Hydrogels serve as a model system to explore mechanisms of deformation and energy dissipation associated with the brittle failure scenario of such soft solids.
This mini-symposium focuses on modeling and experiments of failure mechanisms (e.g. fracture and creep) of hard and soft materials with emphasis on the linking of different length scales, the multiscale description of the fracture pattern and that of the crack propagation. Quantitative comparison of the rupture of hard and soft solids should trigger enlightening exchanges. Moreover, the symposium will bring forward the link between the macroscopic failure scenario and the microstructure of solids by focusing on promising strategies of material design."

This symposium aims to promote collaborations among academic researchers and industrial engineers in developing and applying damage models and related numerical methods to the prediction of nonlinear behaviour of engineering structures. Those who have been working on related fields are cordially invited to exchange their ideas and research outcome in this mini-symposium.

"Geomaterials, such as soil, rock and concrete, are multiphase porous materials whose macroscopic mechanical behavior is governed by grain size distribution and mineralogy, fluid-saturation, pore space, temperature, loading paths and rate, drainage conditions, chemical reactions, and other factors. As a result, predicting the mechanical response of geomaterials often requires knowledge of how several processes, which often take place in different spatial and temporal domains, interact with each other across scales.

"This mini-symposium aims to achieve a follow-up effort of the National Science Foundation (NSF) International Workshop on the “Genome of Stone-based Civil Infrastructure Materials”, which was held at the University of Science and Technology in Beijing, China in May 2016. The workshop included participation of leading researchers and scholars who has worked on fundamental physics-mechanics-chemistry of various types of stone-based civil infrastructure materials (such as hydrated cement concrete, bituminous materials, unbound aggregates, human-augmented soils, etc.) to develop a roadmap to help answer some of critical questions such as (1) what is the genome in civil infrastructure materials? (2) how can one identify the materials genome and evaluate the influence of the materials genome on material properties? and (3) how will the understanding of the materials genome speed up discovery-innovation in materials design? The two-day workshop resulted in a few action items which are to promote knowledge-technology exchange between participants (and anyone else who would be interested in the theme) and to promote international collaboration for research and education.
We wish this mini-symposium can provide an opportunity to keep the momentum rolling so that the fundamental theories and approaches on civil infrastructure materials from the view of the “materials genome” can be a basis for the next generation design-analysis-retrofit-construction-maintenance methods for civil infrastructures. This would be achievable through the better understanding of relationships between the materials genome, the properties of materials, and the performance of infrastructure systems.
The material genome can be described in terms of the material composition, the microstructure, and the inherent defects and can be determined by material characterization methods at multiple length-time scales through various experimentations, numerical simulations, and integration of those. With the availability of high performance computational methods and tools, multiscale modeling based on actual composition and the microstructure of materials can speed up the material design process with significantly reduced costs and time. Presentations are invited on topics related to multiscale and multiphysics modeling of various civil infrastructure materials.
Topics of interest include, but are not limited to:
• Multiscale modeling/simulation/experiments of infrastructure materials;
• Coupled mechanics modeling/simulation/experiments of infrastructure materials;
• Chemo-mechanics and atomistic/continuum coupling;
• Inelastic behavior and damage-fracture of infrastructure materials;
• Advanced nanotechnology and nanomaterials for civil infrastructure;
• Microstructural analyses/modeling of infrastructure materials with interface behavior and/or environmental effects;

MS 63 Recent Advances in Constitutive Modeling for Geotechnical Engineering

Samuel Yniesta - Ecole Polytechnique de Montreal
Katerina Ziotopoulou - UC Davis

"Constitutive modeling in Geotechnical Engineering has become an increasingly active research area over the last few years. With numerical methods and platforms and commercial software having reached powerful computational (and storage) capabilities, the spotlight has turned towards the capabilities and limitations introduced to our simulated systems by constitutive models for soils. At the same time, newly emerging materials (e.g. bio-cemented sands) necessitate the development of constitutive models that are capable of capturing the materials’ elemental behavior and thus are able to simulate and predict their response in the field.
The challenge of modeling all aspects of soil’s (mechanical) behavior under various loading conditions and for the broad range of applications and soil types has yielded significantly more theoretical approaches to soil modeling and the implementation of the models. This increase has resulted in a greater number of available constitutive models with varying degrees of complexity and usability. Due to the plethora of available constitutive models for soils, researchers and practitioners need to know: 1) which constitutive models are available and at what capacity (formulation, implementation, compatibility with platforms), and 2) what a given model may or may not be able to do for the range of behaviors applicable to the problem at hand.
This mini-symposium aims to present the latest advances in the development, formulation, validation, and implementation of constitutive models in all disciplines of Geotechnical Engineering. It also intends to provide a forum in which constitutive modelers can identify needs, share ideas, and develop new directions of collaboration on future research projects. Areas of interest include but are not limited to:
− Geoenvironmental engineering
− Earthquake engineering: cyclic loading of soils, liquefaction, and soil-structure interaction
− Soil modeling in 1D, 2D and 3D ground response analyses
− Unsaturated soil mechanics
− Behavior of unconventional soils such as organic soils and municipal solid waste
− Behavior of bio-cemented soils
− Thermal interactions in soils"

"Nearly every product or commodity in use is constituted and/or derived from granular materials through mining, agriculture, and/or chemical processing. Granular materials are also central to geomechanics and the design of foundations and earthworks. As ubiquitous constituents of industrial processes and geophysical phenomena, these materials exhibit behaviors ranging from rapid, collision-dominated flows to quasi-static deformations. Granular systems also share common properties over a wide range of particle sizes, from rockfills to fine powders, and for colloidal multi-phase materials. On the other hand, their macroscopic properties are entirely dependent on the microstructural and micromechanical properties of their grains and their interactions. As such, suitable attention should also be paid to grain shape and cohesive forces.

This symposium encourages fundamental contributions on:
1) complex behavior at extended scales of density, grain size, and deformation rate
2) complex interactions between grains, fluid, boundary conditions, and temperature
3) transition of granular systems from a solid to fluid-like state
4) fundamental mechanical interactions between particles
5) innovations in discrete element methods with fast contact detection, multi-phases, and parallel computation
6) dynamical systems and multi-scale modeling of flow
7) the interface between granular materials and colloidal systems
modeling granular materials as enhanced continua

The symposium will address granular media from micro- to the macro-scales, including granular modeling, continuum modeling, discrete micro-mechanics, and the micro-macro transition. Contributions on the various aspects of this topic are welcome, including experimental, analytical, computational and theoretical studies. A student competition is being planned as part of the mini-symposium."

"Multifunctional materials are materials that have been intentionally engineered to exhibit more than one precisely defined property or functionality. These materials are encoded with desirable properties, such as damping, piezoresistivity, piezoelectricity, photoelectricity, magnetostriction, self-healing, and load-bearing, among others, and manufactured using methods like “bottom-up” nano-assembly. In particular, an application area of interest is in structural engineering, where resilience to environmental effects and extreme events require that structural materials exhibit unprecedented strength and toughness yet be able to simultaneously sense, resist, and respond to damage. The design of these innovative high-performance materials also need to be achieved without increasing form factor, weight, and costs. These research challenges have spurred tremendous interest in this area, and recent advances include the development of multifunctional composites, structural coatings, sensors/actuators, and autonomous structural systems. This mini-symposium is soliciting contributions ranging from their development to numerical modeling to laboratory testing and to applications, particularly for enhancing the performance, sustainability, and public safety of structural systems.

MS 93 Control of Structures for Multiple Hazards

Aly Mousaad Aly - Louisiana State University

"Wind, wave, and seismic hazards, coupled with aging and vulnerable structures, pose the potential for damage and loss of life and property. Multiple hazard forces can wreak catastrophic damage to buildings, bridges, offshore structures, and the infrastructure in general. Although an individual hazard may be more significant than the other, the rapid population growth and economic development have greatly increased the potential of exposure to multiple hazards. Current design codes and hazard mitigation strategies treat hurricanes and earthquakes completely independent, which does not account for the increased risk to structures in regions where both hazards are present. Consequently, vibration control of structures is indispensable to achieve desired system-level performance under lifetime single and multiple hazard loadings. To do so, several control techniques can be employed. In this mini-symposium, we solicit research presentations focused on the state-of-the-art techniques and methods employed for the control of structures under multiple hazards. Potential topics may include, but are not limited to:

- Vibration control in buildings for wind and earthquakes;
- Vibration control in bridges for wind and seismic hazards;
- Vibration control in offshore structures for wind and waves;
- Vibration mitigation in flexible structures for improved resilience and performance under synoptic and non-synoptic wind loadings;
- Aerodynamic optimization under synoptic and non-synoptic wind loadings for improved sustainability with resilience benefits

MS 102 Multiphysics and Multiscale Modeling of Engineering Materials

Chung R. Song-University of Nebraska-Lincoln
Yong-Rak Kim-University of Nebraska-Lincoln
Huiming Yin-Columbia University

"Recently, there has been increasing interests/foci and developments on the multiphysics-multiscale nature of materials research in many different disciplines. It is because many engineering problems have multiple length/time scales and are subjected to multiple physical phenomena (e.g., kinetic, hydraulic, thermal, etc.). Even though multiphysics-multiscale problems have long been studied in Mathematics, the current excitement is driven mainly by the use of the models in the applied science and engineering. Problems are often multiphysics in nature; namely, the processes at different scales are governed by physical laws of different character: for example, quantum mechanics at one scale, classical continuum mechanics at another, and the material behavior at nanoscale or mesoscale often crucially depends on the bridging techniques of different scales. Properly executed multiphysics-multiscale modeling techniques can vastly improve accuracy and efficiency in solutions which were never possible in the past, in many cases, with very reasonable experimental-computational costs.
Given the technological significance and increasing interests, we propose this mini-symposium to discuss/introduce various (physical, mathematical, computational, and experimental) approaches and their integration into the multiphysics-multiscale modeling of materials. Presentations are invited on topics related to multiphysics and/or multiscale modeling of various engineering materials that may also be incorporated with inelastic constitutive behavior. Topics of interest include, but are not limited to:
• Coupled mechanics modeling/simulation/experiments of engineering materials;
• Multiscale modeling/simulation/experiments of engineering materials;
• Atomistic/continuum coupling;
• Inelastic behavior and damage-fracture of materials in multiple scales;
• Materials-structures interaction with environmental effects;
• Quasi-continuum and equivalent continuum approaches;
• Advanced nanocomposite-nanomaterials systems and nanomechanics;
• Effects of impurities on mechanical properties of composites."

"The field of uncertainty quantification that includes the characterization and propagation of uncertainties associated with complex systems has received considerable interest in recent years. A major portion of the engineering dynamics/mechanics community has focused, with considerable success, on problems with stochastic media properties, random excitations and uncertain initial/boundary conditions. Nevertheless, the development of novel mathematical tools and of potent signal processing techniques, the ever-increasing available computational capabilities, and advanced experimental setups offer a unique novel tool for addressing complex problems for the first time and even posing new questions. Specifically, researchers and engineers are faced with the challenge of interpreting and translating measured data at multiple scales into pertinent stochastic models. In this regard, there is a need for developing robust multi-scale statistical descriptors and stochastic models capable of capturing complex uncertainty relationships. Further, there is a need for developing analytical/numerical methodologies for solving nonlinear high-dimensional stochastic (partial) differential equations efficiently, and for propagating uncertainty across various scales in the time and space domains.
The objective of this MS is to present recent advances and emerging cross-disciplinary approaches in the broad field of numerical methods for engineering stochastic dynamics/mechanics with a focus on uncertainty modeling, and propagation. Further, this MS intends to provide a forum for a fruitful exchange of ideas and interaction among diverse technical and scientific disciplines.

"Almost every physical quantity in problems related with Civil Engineering in general, and Engineering Mechanics in particular, is affected by uncertainty, to some extent. Engineers have the role to identify the cases in which an accurate model of such uncertainty is essential to capture correctly the features of the problem at hand. This Minisymposium will collect contributions to the state-of-the-art and the state-of-practice for models of uncertain quantities defined over and correlated across spatial and temporal domains. These random functions (i.e., random processes and fields) are one of the cornerstones of current research, education, and practice touching problems related with structural reliability, hazard modeling, risk assessment, and uncertainty quantification in general. Nevertheless, there are still substantial challenges associated with the characterization, simulation, optimal sampling, and computationally efficient manipulation of random functions, especially when they are non-Gaussian and non-stationary. Leading scholars will be invited to discuss their most recent advancements on the following topics and beyond.
- Mathematical theory of random functions (e.g. wavelet decompositions, optimal series expansions).
- Characterization of random functions (e.g. spectral, statistical, and Bayesian methods).
- Simulation of random functions (e.g. Karhunen-Loeve expansions, spectral representation).
- Optimal sampling of random functions (e.g. stochastic reduced-order models, functional quantization, random sampling).
- Solution strategies for engineering problems involving random functions, such as systems with temporally varying random input, or systems with uncertain and spatially varying material properties (e.g. stochastic ODEs, PDEs).

"Rapid advancements in manufacturing technologies, experimental and measurement devices, and computational science are producing a paradigm shift in our ability to anticipate the behavior of complex systems. Reliable accounts of the properties and the behavior of such systems encompass a combination of expertise from experimental, physical, computational, and statistical sciences. It has now become possible to address some of the challenging questions pertinent to the behavior and design of complex systems including those that exhibit coupling across multiple physics and multiple scales.
The field of uncertainty quantification offers tools that allows the rational and credible inference of properties and behavior of complex systems. Throughout this process and in order to construct robust predictive models, it is vital to appropriately account for uncertainties and errors associated with multi-physics and multi scale coupling.
In general, the assimilation of experimental measurements is governed by limitation in the quantity and sometimes quality of available data and by incomplete knowledge about the physics. In many cases, it is not possible to directly measure the quantities of interests.
Contributions to this minisymposium will include various aspects of the stochastic computational treatment of complex systems. Such systems include, for instance, random heterogeneous media (e.g., composite materials, infrastructure materials, etc.) and systems whose behavior exhibit coupling across physical processes and spatio-temporal scales. The stochastic computational treatment could include, but not limited to, model-based risk assessment and mitigation, forward propagation of uncertainties, stochastic calibration and optimizaton, stochastic modeling and upscaling, as well as stochastic data assimilation and model updating across physics and scales.

MS 132 Safety Assessment of Aging Infrastructure: From Data to Decision

Suparno Mukhopadhyay -IIT Kanpur, India
Simos Gerasimidis -University of Massachusetts Amherst, USA
Raimondo Betti - Columbia University, USA

"The safety assessment of any infrastructure system requires both (a) the knowledge of the expected demands on the system, as well as (b) a measure of its current capacity. Using such information in forward analyses, the safety and functionality of the infrastructure system can be assessed, and, if necessary, appropriate maintenance/retrofitting/control strategies can be designed to counter any loss of capacity or unexpected growth in demand. With the rapid advancement of a variety of data measurement systems, many present day approaches for demand and capacity estimations are data-driven. This mini-symposium aims to provide a platform for discussing this multi-faceted nature of data-based structural safety assessment. Abstracts are invited on:
• identification and statistical modelling of input excitations from measured infrastructure response data and/or direct input measurements
• using continuous monitoring and environmental data for modelling global and/or component level deterioration of aging infrastructure systems, as well as data-based methods for updating such deterioration models
• efficient data-based approaches to quickly detect degradation in condition and/or performance of aging infrastructure
• approaches for identifying or updating physics based (e.g. finite element) models of infrastructure systems using monitoring data
• approaches to quantify uncertainty in identified input models, infrastructure deterioration models and updated structural models
• use of identified input, deterioration, and updated structural models in infrastructure safety assessment through forward analysis (e.g. collapse analysis)
• assessing the effect of localised deterioration on the structural stability of members and systems
• stability-induced collapse of aging systems
• incorporating uncertainties in input, deterioration, and updated structural models in safety assessment, and approaches to improve computational efficiency in such probabilistic forward analysis
• experimental and real-life applications of new/existing methods in the above areas
• case studies on use of measured data in designing of retrofitting or control strategies

MS 143 Infrastructure system integrity through damage precursor sensing

Marcus P Rutner - Stevens Institute of Technology
Ed M Habtour - U.S. Army Research Laboratory
Branko Glisic - Princeton University

Infrastructure systems built out of conventional or new materials undergo aging and deterioration. Continuous information on the condition, the performance level, and the remaining service life of the infrastructure system is required to ensure system safety and is of economic value since maintenance costs increase non-proportionally the longer the defect stays undetected. Most defects are on the micro-length scale when becoming critical, hence are difficult to detect per visual inspection or with conventional sensing technology. This mini-symposium is inviting innovative sensing technologies which enable defect detection and characterization of micro-size defects or so called damage precursors through real-time automated or on-demand sensing. Further, the mini-symposium provides a platform for time-efficient and reliable damage prognostics working with the sensed data. The proof of conceptual ideas, computational approaches, and particularly laboratory and field test results of damage precursor sensing, damage diagnostics and prognostics methodologies are of interest. The mini-symposium invites contributions from all industries and is expected to raise interest among attendees from academia, government agencies and industry.

MS 144 Inverse problems for tomographic imaging and remote sensing applications in engineering

Fabio Semperlotti - Purdue - Mechanical Engineering
Tyler Tallman - Purdue - Aerospace Engineering

"During the last two decades, the interest of the scientific community in the development and implementation of tomographic technologies have undergone a drastic growth. Owing to its intrinsic potential and to the growing need for non-destructive techniques in many fields of science and engineering, tomographic technology has quickly spread to a variety of disciplines including, but not limited to, biomedics, geophysics, oceanography, structural health monitoring, and non-destructive evaluation of materials.
The sudden extension of these technologies to the engineering community at large has not been followed yet by dedicated technical symposia and opportunities for interactions between different disciplines.
Considering the already existing strong technical content in inverse problems, structural identification, and data processing, EMI is an excellent venue to host a mini-symposium dedicated to cutting edge technologies and applications of tomographic imaging and remote sensing in engineering. This symposium provides an ideal environment for cross-pollination of ideas and exchange of theoretical/numerical/experimental methodologies for tomographic and inverse problems between the most diverse fields of engineering.
This symposium was organized for the first time at EMI 2015 in Stanford and had a very good turn out with about eight authors participating. We organized the symposium also at EMI 2016 in Vanderbilt also with a very good turnout of presenters and, particularly, a very large attendance. We have seen the symposium growing over the past couple of years and we believe that, by making it a recurring appointment at EMI, it will have the potential to become an excellent platform for this line of research in the United States."

  Structural Instability
MS 151 Mechanical behaviour and stability of shell structures totally or locally confined

Frederic BUMBIELER - Andra (French national radioactive waste management agency)
Ali LIMAM - LMC2 - Université de Lyon, France

"The intent of this symposium is to bring together researchers investigating the mechanical behavior of confined structures and components. In many civil, mechanical and aerospace engineering applications (tunnel supports, buried pipelines or tanks, sandwich structures, steel shells reinforcement …) shell structures are subjected to various (thermo)mechanical loading conditions while being confined within a total or partial surrounding medium or adjacent structures in contact. In most cases an external mechanical load is applied on the confined structure, sometimes itself subjected to a thermal load and a possible progressive degradation (corrosion, plasticity, microcracking, …) so that it will buckle when a critical level of compressive stresses is reached or a critical amplitude of geometrical imperfection is obtained due to material creep. If it is well known that a confined structure will buckle at higher pressure than an unconstraint one, its overall mechanical behavior is strongly dependent on the properties of the confining medium and contact conditions (with adhesion or not), the external loading characteristics (stress or displacement loading, hydrostatic or anisotropic), but also material creep with a weak or strong interaction with defects or damage depending their wavelength.
This symposium will bring together the structural engineering industry with academia aiming to provide insights on the actual engineering mechanics of locally or totally confined structures. Topics relevant to the session include (but are not limited to): analytical and numerical investigations of the stability of steel, composite, concrete and/or multilayered confined structures, experimental techniques for mechanical behavior and stability tests on mock-up, in-situ measurements of the mechanical behavior of confined structures, buckling and post-buckling analysis (theoretical and experimental) of sandwich confined structures.
The initial speakers list includes Stelios Kyriakides (University of Texas at Austin), Spyros Karamanos (University of Thessaly), Hassan Karampour (Griffith University), Theodoro Netto (Federal University of Rio de Janeiro), Ali Limam (University of Lyon), The Nguyen (INSA de Lyon), Dinh Cuong (INSA de Lyon), Mohammed Hjiaj (INSA de Rennes), Frédéric Bumbieler (Andra)"

MS 152 Robustness of Infrastructures (Progressive Collapse)

Simos Gerasimidis - Assistant Professor, University of Massachusetts, Amherst
George Deodatis - Professor, Columbia University

On the forefront of structural engineering mechanics problems today lays the problem of robustness or progressive collapse. The aging of infrastructures and the very high multilevel consequences associated with the phenomenon have raised progressive collapse as one of the most important structural engineering mechanics problems. Progressive collapse can be initiated by numerous sources including construction or design flaws which surpass the common design base of current codes. Triggering events can be extreme events such as earthquakes, hurricanes, floods, abnormal loads not included in the design like gas explosions, vehicle impacts, fire or extreme environmental loads which push the structural system well beyond its strength envelope. In this framework, all infrastructure is vulnerable to progressive collapse at some level. This mini-symposium will bring together the structural engineering industry with academia aiming to provide insights on the actual engineering mechanics of progressive collapse.

MS 162 Harnessing Elastic Buckling/Postbuckling Response for Sustainable and Resilient Infrastructure

Rigoberto Burgueno - Michigan State University
Han Hu - Dartmouth College

A change in perspective has emerged during the past decade towards the harnessing of elastic structural instabilities for “smart” purposes in a variety of avenues. Among the different types of unstable responses, buckling is a phenomenon that has been known for centuries, and yet it is generally avoided through special design considerations. Other than the well-known effect on load-carrying capacity, buckling also involves high-rate motion and sudden energy release. These two features make buckling an ideal mechanism for adaptive and smart applications. Thus, increasing interests in the design of smart devices and mechanical systems have identified elastic buckling and postbuckling response as favorable and increasing studies are demonstrating the use of such behavior across disciplines. A community of scholars focused on this research topic has grown rapidly over the past 10 years. Buckling behavior is controlled primarily by the geometry of slender elements, and the particular interest on elastic response makes it applicable across scales. Considerable research is being conducted to understand the mechanics of elastic buckling and postbuckling response for a variety of structural prototypes with particular emphasis on applications to devices. Studies on 1D (beams) and 3D (cylinders) forms range from applications to energy harvesting, sensing, and energy dissipators. While research attention is strongly leaning towards lower-scales for developing mechanically-engineered materials, usage in macro-scale devices and structural elements is becoming clear and activity on this front is emerging. The aim of the proposed symposium is to provide impetus to this emerging focus by bringing attention to the harnessing elastic buckling and postbuckling response for innovations in sustainable and resilient infrastructure. The symposium will allow participants and attendants to exchange findings from current research activities and to identify emerging trends.

Mohammed Ettouney- Mohammed Ettouney, LLC

"Resilience emerged lately as a major issue for society, especially given the magnitude of disaster costs of different kinds. As any emerging important issue, the knowledge gaps within the subject of resilience are enormous. The Objective Resilience Committee (ORC) of the Engineering Mechanics Institute (EMI) of the American Society of Civil Engineers (ASCE) is developing an Objective Resilience Primer (ORP) which aims at exploring some of the issues regarding objective resilience. The ORP includes four parts. Part I addresses resilience definitions, standards, and social and economic subjects. Part II addresses processes and methodologies including variables, links, graph networks and uncertainties. Part III focuses on different technologies which might be of help in objectifying resilience and Part IV looks at applications, including different components of resilience management as applied to several types of civil infrastructures such as buildings, bridges, mass transit stations and tunnels.
The proposed mini symposium will include presentations from different authors of the chapters of the MOP. The presentations include, but not limited to: from part I: resilience definitions, resilience standards, and resilience initiatives. From part II, the presentations include different resilience dimensions, networks methods, uncertainties, acceptance, communications and links. Part III presentations includes advanced materials, remote sensing and structural health monitoring as applied to enhancing resilience performance. Finally, part IV presentation offers pertinent case studies and applications."

MS 165 Sustainable and Resilient Structural Engineering, Mechanics, and Materials (SR-SEMM)

Fariborz M. Tehrani - California State University, Fresno
Arezoo Sadrinezhad - California State University, Fresno
Maryam Nazari - California State University, Fresno

This Mini-Symposia (MS) aims to provide a forum to discuss recent advancement in the area of sustainable and resilient structural engineering, mechanics, and materials (SR-SEMM). The topic of sustainable built environment has been the major focus in academic research and industrial practice, particularly in the field of SEMM. The rise in climate-related-disasters, constant challenges in energy sector and substantial shift in consumer’s conscious toward conservation of natural resources are the major forces behind sustainable engineering. Further, sustainability and resilience of infrastructures contribute to their long-term efficiency and serviceability. Many code-writing bodies have developed guidelines and specifications to implement sustainable practices and rate their impacts. Although, many professionals are familiar with common sustainable practices recognized by these documents, they are not necessarily comfortable with implementation of innovative materials and methods in engineering mechanics, such as composites, upcycled materials, bio-inspired materials, and Nano-mechanics. Moreover, appraising the feasibility of any sustainable practice requires knowledge of analytical procedures, including lifecycle cost analysis (LCA) and decision-making tools, in a context-sensitive design. Further, production, transportation, and application of materials require additional resources, like energy and land, and cause additional impacts, including greenhouse gases, noise, and pollution. Following ENVISION guidelines for rating sustainable practices, this MS seeks research and practice papers on how SR-SEMM contributes to (a) reduction of net-embodied energy, energy consumption, and water consumption, (b) reduction of land and water contamination, greenhouse gas emissions, and air pollutant emissions, (c) enhancing long-term adaptability and extending useful life of infrastructures, and (d) minimizing noise, vibration, and other adverse impacts on communities.
