Computations of Microstructure
Charles R. Collins
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.
