Numerical Methods for Material Systems with Microstructure

Abstract

The objective of this project was to develop an emerging, stabilized finite element method for treating general interfacial laws and microstructural representations independently of a background finite element mesh. Major research objectives and accomplishments associated with the project include: 1) extension of the basic approach to account for dissipative bulk and interfacial phenomena, such as crystal plasticity and grain boundary sliding, and the adaptation of the approach to explicit dynamics; 2) the leveraging of numerical analysis to greatly improve the efficiency of the method, and the exploitation of methods for multi-scale coupling to continuum models; and 3) the training of a broad range of graduate students in the use of these methods.
