Modeling Software and Tools for Reliability Engineering of Micro/Nano-Device Systems and Components

The ability to develop new generations of superior military systems and civilian products requires the use of multifunctional materials and ever smaller components for which key design parameters are associated with nano-scale constituents. The ability to understand and design these materials and components requires the application of multiscale simulation technologies that can account for interactions across many decades of spatial and temporal scales starting from the atomic scale. The goal of this project is to build on the research efforts on multiscale modeling of the past decade to develop a set of integrated computational methods and associated software components that seamlessly couples and spans multiple spatial and temporal scales needed in the simulation of systems that are subject to thermal and shock loading. To meet this goal the areas to be considered include (i) determination of the models and scale linking functions required for non-equilibrium problems subject to a combination of high speed thermal and mechanical loads, (ii) the adaptive methods needed to ensure reliability of multiscale analysis, (iii) methods to execute the massive computations required on parallel computers and (iv) verification and demonstration of the methods developed on problems of interest to the Army.
