Abstract : The goal of this project, which was part of the DARPA Balanced Technology Initiative on Computational Mechanics, was to develop a comprehensive approach to the numerical modeling of the mechanical behavior of materials. Particular areas for focus in the project were the inelastic deformation of highly anisotropic materials such as single crystals and textured polycrystals, as well as evolving microstructural damage in ceramics and ductile metals in both slow and high rate deformation processes. While the contract was awarded for a period of three years, it was actually funded only for the first year. Nonetheless, significant progress can be reported as a direct result of this project....
