EMI-MS-03: Robustness of Infrastructures (Progressive Collapse)

George Deodatis, Columbia University
Simos Gerasimidis, University of Massachusetts, Amherst

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 minisymposium will bring together the structural engineering industry with academia aiming to provide insights on the actual engineering mechanics of progressive collapse.

EMI-MS-16: Multiphysics and Multiscale Modeling of Engineering Materials

EMI Modeling Inelasticity and Multiscale Behavior Committee

Dr. Chung R. Song, University of Nebraska
Dr. Yong-Rak Kim, University of Nebraska
Dr. Ahmed Al-Ostaz, University of Mississippi

The modern techniques to analyze the behavior of materials are well developed for scientists to attempt to build a colony in outer space. It is, however, true that there are many things in which scientists still do not have very good idea how to analyze it. Multiphysics and Multiscale modeling disciplines are some of these area.
Properly executed Multiphysics and Multiscale modeling techniques may provide solutions which were never possible in the past, in many cases, with very reasonable computational cost. An example of Multiphysics includes the coupled analysis of Kinetic-Hydraulic-Thermal analysis of an earthen dam, so that the structural condition of the dam is obtained from the temperature data of the dam. An example of Multiscale Modeling includes the incorporation of Nanomechanics, Micromechanics and Macromechanics to obtain the detailed behavior of real world materials reliably and very cost effectively.

• Coupled mechanics simulation of engineering materials and structures.
• Multiphysics modeling of engineering materials, structures and phenomena.
• Multiscale modeling and simulations of nano structured materials.

Chandrasekhar Annavarapu, Lawrence Livermore National Laboratory
Timothy Truster, University of Tennessee
Ravindra Duddu, Vanderbilt University

The intent of this symposium is to bring together researchers investigating the mechanics and physics of interfaces, including free boundaries or surfaces. Interfaces are a critical physical feature of many natural and engineered systems. The computational modeling of such systems is complicated by evolving discontinuities, capturing local spatial and temporal scales that can be orders of magnitude below the system scales, as well as the formation and/or interaction of free surfaces. Problem classes include, but not limited to, contact and friction between deformable bodies, delamination or fracture in materials, localization or boundary layer tracking, fluid-structure interaction, and growth instabilities in biological/material systems. Computational techniques that address stability issues in interface methods and imposition of interface conditions, such as, mortar finite element methods, discontinuous Galerkin methods, extended/generalized finite element methods (XFEM/GFEM), Nitsche methods, mixed interpolation methods, and embedded mesh methods are welcome. Submissions that relate to either the development of such methods or their application to engineering problems are encouraged.

Marcus Rutner, Stevens Institute of Technology

This mini-symposium provides a platform for knowledge dissemination and exchange of innovative ideas concerning the latest developments in the field of nano- and microstructured materials contributing to form the next generation of materials superseding conventional materials. Computational modeling and experimental test methods providing new insights into e.g. the thermal, mechanical, electrical properties of different phases of nano- and microstructured materials and findings on how composition and microstructure affect bulk material behavior are expected contents of this mini-symposium. New findings in processing, testing, measuring and installation of nano- and microstructured materials are of interest. The design of many nano- and microstructured materials is based on empirical approaches and the fundamental materials physics is still unknown. Contributions which shed light on the fundamental physics of nano- and microstructured materials are of particular interest since these insights will enable physics-based design capability advancing the material performance. This mini-symposium is inviting contributions exploring the properties of technologically-important materials which are strongly controlled by their internal nano- and microstructure.

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 on how several processes, which often take place in different spatial and temporal domains, interact with each other across length scales.

This mini-symposium is intended to provide a forum for researchers to present contributions on recent advances in Computational Geomechanics. Topics within the scope of interests include, but are not limited to, the following: (1) development and validation of constitutive models that address multi-physical coupling effects, (2) discrete and continuum formulations for geomechanics problems, (3) iterative sequential couplings of fluid and solid solvers, (4) uncertainty quantification for geomechanics problems, (5) multiscale mechanics, (6) modeling of weak and strong discontinuities, (7) regularization techniques to circumvent pathological mesh dependence, and (8) techniques to model crack growth and fragmentation processes in geomaterials.

EMI-MS-20: Computational Geomechanics for Subsurface Energy Resources Exploitation

Poromechanics Committee

Shunde Yin, University of Wyoming
Patrick Selvadurai, McGill University

Drilling, injection and/or production are major activities in exploitation of subsurface energy resources. Mechanical behavior of involved geomaterials (rock, shale, soil) and their fracture is the key to assessing the efficacy and environmental concerns associated with these activities. Understanding the mechanical behaviors of geomaterials and their fracture requires knowledge of their interaction with heat transfer, fluid flow, and sometimes chemical and biological reactions. Computational geomechanics provides powerful tools to investigate geomaterials and their fracture behavior in these activities.

This mini-symposium will discuss both fundamentals and applications of computational geomechanics involved in these activities. Abstracts on or related to these topics are all welcome.

The mechanics of engineering materials often depends on nanoscale interactions between solid skeleton and pore fluid. The magnitude of the interactions becomes very large in mesopores and micropores, where the fluid is highly confined and cannot be considered as bulk. This miniMsymposium aims to address the molecular details of fluid structure and fluidMsolid interaction, and how to incorporate the nanoscale action of fluid (e.g. disjoining pressure) into the current understanding of the mechanics of engineering materials. Contributions will be welcome from a wide spectrum of fluidMmaterial systems and associated phenomena, e.g. waterMdependent moduli of elasticity, creep, and toughness of concrete, clay, wood, and alkaliMactivated cements; organic-inorganic interactions in gas shale; swelling/shrinkage of coal and soils during carbon sequestration. Both theoretical and experimental contributions are welcome, with a combination of both being ideal. Contributions on macroscale modelling, such as poromechanics and homogenization theory, are also appropriate, as long as the focus is on scalingMup the action of fluids in micropores and mesopores.

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. As such, suitable attention should also be paid to grain shape and cohesive forces.

This symposium encourages fundamental contributions on: (i) the complex behavior of granular materials at extended scales of density, grain size, and deformation rate; (ii) the transition of granular systems from a solid to fluid-like state; (iii) fundamental mechanical interactions between particles that control such transitions; (iv) dynamical systems and multi-scale modeling of flow; and (v) the interface between granular materials and colloidal systems. The symposium will address granular media from micro- to the macro-scales, including granular 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.

EMI-MS-25: Advances in Base Isolation

Dimitrios Konstantinidis, McMaster University
Nicos Makris, University of Central Florida

Base isolation is an established earthquake-resistant design approach that has been used in more than 6,000 buildings around the world. Unlike conventional earthquake resistant design approaches that aim at increasing the capacity of the structure, base isolation aims at reducing the demand. This is achieved by decoupling the structure from the ground motion by placing horizontally flexible bearings between the building and its foundation. In recent years, significant advances have been made in base isolation technology, modeling and applications, including elastomeric isolators with adaptive compounds, multi-surface sliding bearings, isolation of individual components and floors, mid-story isolation, isolation for tall buildings, isolation systems for nuclear industry applications, etc. This mini symposium will focus on recent developments in base isolation, aimed at protecting both buildings and their nonstructural components.

The uplifting and rocking of slender, free-standing and weakly restrained structures when subjected to ground shaking may limit appreciably the seismic moments and shears that develop at their base. In view of the need to minimize seismic stresses, permanent displacements, damage and cost, rocking isolation is receiving increasing attention as an alternative seismic protection strategy. This mini-symposium aims to attract recent contributions on the dynamic response of articulated/rocking structures in an effort to bring forward the major advances together with the unique advantages of rocking isolation.

Raimondo Betti, Columbia University

The national infrastructure is aging and its health is deteriorating. The ASCE's 2013 Report Card of America’s Infrastructure condition assigns a C+ grade for bridges, a D grade for roads and dams, and a D- grade for levees (in which C is mediocre and D is Poor). The failure of an infrastructure (such as the levees in New Orleans) due to a natural or man-made hazard can have monumental repercussions, sometimes with dramatic and unanticipated consequences on human life, property and economy. Cyber-physical infrastructures are a new class of sensor-rich systems aimed at an efficient damage detection and localization, health evaluation, and complete management of theses infrastructures. The goal of this mini-symposium is to provide a forum to discuss recent developments in cyber-physical infrastructures including instrumented systems, embedding sensing, large scale monitoring (e.g., of a regional network of levees in New Orleans), computing and decision technologies (e.g., identification and hazard mitigation measures), and smart infrastructure systems in general. Contributions on the various aspects of these topics are welcome.

EMI-MS-34: Infrastructure system integrity through next-generation automated sensing, damage diagnosis and prognosis

Marcus Rutner, Stevens Institute of Technology

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 at an early stage through real-time automated sensing. Further, the mini-symposium provides a platform for time-efficient and reliable damage prognosis working with the sensed data. The proof of conceptual ideas, computational approaches, and particularly laboratory test and field test results of new sensing, damage diagnosis and prognosis 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.

EMI-MS-35: Mechanobiology of Soft and Hard Tissues

Properties of Materials, Biomechanics Committee

Stefan Scheiner, Institute for Mechanics of Materials and Structures, Vienna University of Technology

Biological tissues are usually divided into soft (unmineralized) tissues, such as cartilage or blood vessels, and hard (mineralized) tissues, such as bone. The development of their structure and composition is driven by cellular activities, which in turn are modulated through biochemical and biomechanical stimuli. Considering that several of the underlying processes exhibit significant similarities between soft and hard tissues, the goal of this mini-symposium is the cross-fertilization of the usually separated scientific communities studying these processes 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) 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.

EMI-MS-39: Modeling of grain boundaries and grain boundary-driven mechanics

Brandon Runnels, University of Colorado - Colorado Springs
Irene Beyerlein, Los Alamos National Laboratory

Grain boundaries are a unique type of defect that act as dominant mechanism in mesoscale mechanics including (but not limited to) grain growth, microstructural evolution, plasticity, and phase transformation. Applications for which grain boundary modeling is relevant include additive manufacturing, engineering materials for fracture toughness under shock loading, manufacture of composites, and micro-electro-mechanical systems (MEMS). Consequently it is of great interest and application to account for and accurately model grain boundaries in the context of mechanics. This minisymposium invites abstract submissions on grain boundary-related topics with the following categorizations:
1. Modeling grain boundary anisotropy of energy and mobility in metals and ceramics
2. Computational modeling of grain boundaries in microstructure (using, e.g., atomistic, dislocation dynamics, or phase field methods)
3. Integration of grain boundary anisotropy on other mechanical models (e.g. crystal plasticity, phase transformation)
4. Grain boundary engineering

The focus of this minisymposium is on computational and theoretical methods, but experimental studies with results relevant to modeling efforts are also welcomed.

Topics of interest include, but are not limited to, novel numerical methods and concepts for biomechanics problems, algorithmic and implementation aspects in biomechanics simulations, frameworks for patient specific simulation and computational steering, decision support systems for preoperative planning and optimization, integration of simulation workflows with diagnostic imaging technologies, and model verification and validation.

EMI-MS-41: Inverse problems for tomographic imaging and remote sensing applications in engineering

Fabio Semperlotti, Purdue University

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 would be an excellent venue to host a mini-symposium dedicated to cutting edge technologies and applications of tomography and remote imaging in engineering. This symposium will provide 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 manufacturing technique provides unprecedented design flexibility and is much more efficient than traditional casting or subtractive manufacturing techniques. Though its current use has been mainly limited to the fabrication of monolithic objects with complex shape and geometry, additive manufacturing is opening the door for the creation of novel composite materials by precisely controlling and forming the internal structure and chemistry of the composite material through the addition of ultra‐thin layers of different constituents. This mini‐symposium is to provide a forum for researchers to discuss the use of 3D printing and computational modeling as tools for the invention of novel materials and interfaces with built‐in multifunctional responses. Material systems of interest include polymeric, biological, biomimetic, cement‐based, and metallic materials.

Papers are solicited in the following areas including, but not limited to:
‐ Coupled additive manufacturing, mechanics and materials design
‐ Combined 3D printing and multi‐scale modeling
‐ Microstructure/3D printing relationships
‐ Modeling as tool for engineering and predicting the material properties
‐ Integrated fundamental materials data and modeling

Real-time hybrid simulation (RTHS) is a novel, powerful and cost-effective experimental technique for examining the global behavior of complex, large-scale structural systems under realistic dynamic loading conditions. This technique is developed by coupling both physical and simulated components, and applying advanced algorithms to interface these two components to provide real-time loading rate as the experiment progresses. Recent advances in RTHS are offering better understanding to the fundamental issues in RTHS, and enabling more efficient and cost-effective solutions to the investigation of global structural system behavior under realistic conditions. The goal of this mini symposium is to provide a forum for RTHS researchers to exchange information, disseminate recent findings, and identify future key focus areas in RTHS. This symposium invites papers related to the following aspects of RTHS: numerical integration, actuator control, noise treatment, assessment criteria, stability analysis, innovative hybrid simulation framework, recent RTHS implementations and applications.
