Virtual Design and Testing of Materials: A Multiscale Approach

Abstract

The aim of the work proposed here is the development of a virtual testing and design capability that can be used to test -- and suggest design strategies for -- new advanced structural materials. Our main objective is thus to develop a hierarchy of methods involving both seamless coupling of information from different scales (electronic to atomic; atomic to microstructural; micro- to macrostructural) and information transfer from one level of hierarchy to the next. As a secondary objective, each methodological advance will also be used to investigate specific phenomena at a single scale. The overall outcome of our work will be a coherent set of computational tools and advances in fundamental understanding of many issues in the thermomechanical performance of materials.
