ACME: Algorithms for Contact in a Multiphysics Environment API Version 1.3

Brown, Kevin H.; Brown, Kevin H.; Voth, Thomas E.; Glass, Micheal W.; Gullerud, Arne S.; Heinstein, Martin W.; Jones, Reese E.

An effort is underway at Sandia National Laboratories to develop a library of algorithms to search for potential interactions between surfaces represented by analytic and discretized topological entities. This effort is also developing algorithms to determine forces due to these interactions for transient dynamics applications. This document describes the Application Programming Interface (API) for the ACME (Algorithms for Contact in a Multiphysics Environment) library.

An extended finite element method formulation for modeling the response of polycrystalline materials to dynamic loading

AIP Conference Proceedings

Robbins, Joshua R.; Voth, Thomas E.

The extended Finite Element Method (X-FEM) is a finite-element based discretization technique developed originally to model dynamic crack propagation [1]. Since that time the method has been used for modeling physics ranging from static meso-scale material failure to dendrite growth. Here we adapt the recent advances of Vitali and Benson [2] and Song et. al. [3] to model dynamic loading of a polycry stalline material. We use demonstration problems to examine the method's efficacy for modeling the dynamic response of polycrystalline materials at the meso-scale. Specifically, we use the X-FEM to model grain boundaries. This approach allows us to i) eliminate ad-hoc mixture rules for multi-material elements and ii) avoid explicitly meshing grain boundaries. © 2007 American Institute of Physics.
