Crystals, Defects and Microstructures: The Case for Multiscale Modeling

8:00 AM-8:45 AM
Room: Liberty B&C
Chair: Weinan E, Princeton University and Courant Institute of Mathematical Sciences, New York University, USA

"Multiscale modeling'' has arisen out of the recognition that in many problems there are either multiple length or time scales operating simultaneously. The existence of such problems and both the conceptual and computational difficulties they imply has led to formal efforts to create such models. In this presentation, the speaker will examine two different examples of multiscale modeling associated with the quest to understand plastic deformation in metals. In particular, he will describe recent methodological advances in which atomistic simulation has been united with the finite element method, and highlight the application of this method to dislocations and their interactions.
