This grant provides partial funding to support workshops on Multiscale Modeling for Multifunctional Analysis and Design (MMMAD) and Challenges in Computational Multiscale Materials Modeling (CCMMM) to be held in Arlington, Virginia. These workshops are part of a series of three interdisciplinary workshops that will focus on experimental and computational methods in multiscale analysis and design. The workshops will be held from 2 thru 5 May 2011 and are entitled: (i) Experimental Multiscale Methods (EMM), (ii) Multiscale Modeling for Multifunctional Analysis and Design (MMMAD), and (iii) Challenges in Computational Multiscale Materials Modeling (CCMMM). The workshop series will be sponsored by multiple government agencies, viz. ARO, AFOSR and NSF. The EMM workshop will focus on measurement of deformation and experimental methods across scales. It will also address validation of multiscale models by means of multiscale experiments. The MMMAD workshop will discuss specific challenges pertaining to the development of robust multiscale computational analysis-design platforms for multifunctional materials and structures. The CCMMM workshop will address critical issues that confront the computational multiscale materials modeling research discipline for comprehensive analysis of complex material structure interactions at a broad range of length and time scales. The workshops will address critical challenges and needs in establishing robust spatio-temporal multiscale modeling of material systems.
The potential of the multiscale modeling paradigm is unfathomable at the current stages, given the tremendous growth in various aspects of this discipline. The theme is consistent with current trends in Integrated Computational Materials Science and Engineering (ICMSE) and Simulation based Engineering & Sciences (SBES) to guide the design of novel systems that meet specifications of performance and reliability. The proposed workshop series will bring together researchers from academia, industry and national laboratories to identify major challenges and research objectives for developing robust multiscale modeling and design platforms. A comprehensive report will result from this workshop which will be an important roadmap for future strategic developments in this field.
The NSF grant supported three activities, two workshops and one conference/workshop. They are: 1. NSFworkshop on Multiscale, Multiphysics Analysis & Design for Multifunctional Applications (MMADMA), Arlington, Virginia on May 3, 2011. 2. NSF workshop on Challenges in Computational Multiscale Materials Modeling (CCMMM), Arlington, Virginia on May 4, 2011. 3. Partial support of a conference, "22nd International Workshop on Computational Mechanics of Materials (IWCMM XXII)", Baltimore, Maryland on September 24-26, 2012. Somnath Ghosh of Johns Hopkins University chaired both workshops and the conference. The MMADMA workshop addressed specific challenges pertaining to the development of robust multiscale computational analysis-design platforms for multifunctional materials and structures. In the near future these kind of techniques could be used for the development of next generation of intelligent structures that can be components of small unmanned airborne vehicles, active skins for spacecraft, aircraft, automobiles and watercraft or next generation meta-materials for optical and communication systems. This workshop dealt with (i) spatio-temporal multi-scale modeling of multi-physics problems involving multi-phase, multi-constituent material microstructures, and (ii) effective multi-scale design methodologies for location-specific optimal functionalities. The innovative analysis-design framework can be adapted to a range of new applications from nano-devices to smart electronic skins and conformal antennas. The CCMMM workshop addressed critical issues that confront the computational multiscale materials modeling research discipline for comprehensive analysis of complex material structure interactions at a broad range of length and time scales. The demands on future engineering systems and structural components with respect to performance, durability, and reliability under severe thermo-mechanical and environmental conditions are challenging the operational limits of monolithic and heterogeneous materials, such as metals, ceramics and composites. Applications encompass nano-scale structures to more scales of components in the automotive, aerospace or energy sector. Furthermore, they can operate at a range of time scales depending on the physical scale of the problem. Solving these challenging problems require comprehensive understanding of material behavior and their subsequent design at a wide range of length and time scales and establishing links between them. It is evident that powerful full-field multiscale predictive capabilities are essential to identify interacting phenomena at different scales, critical phases, as well as dominant mechanisms at different spatial and temporal scales. The 22nd International Workshop on Computational Mechanics of Materials provided a forum for bringing together researchers and practitioners from academia, industry, government and laboratories all over the world to discuss latest advancements and future directions in various areas pertaining to computational mechanics of materials. It covered all aspects of modeling and simulations of the mechanical behavior at different length and time scales. The materials of interest ranged from traditional materials such as metals, alloys, polymers and composites to advanced and emerging materials and bio-materials. It was perceived that all of these three events had high levels of success with respect to the objectives laid out and distinguished participants were able to contribute significantly to the mission of the workshops.
