Challenges in Integrated Computational Structure - Material Modeling of High Strain-Rate Deformation and Failure in Heterogeneous Materials

Abstract

Abstract : This is a final report on a workshop entitled Challenges in Integrated Computational Structure-Material Modeling of High Strain-Rate Deformation and Failure in Heterogeneous Materials that was held at Johns Hopkins University on September 5-6, 2013. The event consisted of 2 introductory talks, 11 plenary talks and a host of panel discussions. The talks and panel discussions were able to identify areas of opportunities that exist with respect to future research directions sponsored by the Army Research Office in the field of Solid Mechanics. Serious gaps remain in a consistent approach for integrated computational material-structure modeling that is needed for developing predictive capabilities of high strain-rate deformation, damage and failure in heterogeneous materials for DoD applications. The Computational Mechanics and Mechanics of Materials communities have made important strides towards advancing modeling capabilities in dynamic material behavior. However a comprehensive integrated approach, coupling novel developments and innovations in the fields of multi-scale computational mechanics and materials engineering, leading to prediction of structure-materials response and failure behavior is still missing. Development of a framework that couples multi-scale computational mechanics, materials science, and experiments for response of failure analysis under dynamical loading is seen as an important initiative that can be advanced by ARO.
