Computations of Microstructure


Professor Charles R. Collins

Abstract

A defining feature of many modern materials is their ability to form a microstructure in response to external stimuli. An example of this is the fine-scale bands called twinning which occurs in the shape memory alloys. One approach to studying these structures is to model the energy density of the material with a multi-well potential, with the wells representing the various components forming the microstructure. Then energy minimizing configurations are studied to determine properties of the microstructure.

In this talk, I will describe a computational approach to determining these energy minimizing configurations and I will present the results of large-scale computations which exhibit realistic microstructures.
