Calculation of Elastic-Plastic Wave Propagation on the Connection Machine

Abstract

This report describes the parallel algorithms and data structures for implementing a 2-D multimaterial kernel of the wave-propagation code, HULL, on a Connection Machine. Computational performance is illustrated for a rod-plate impact problem with material strength described through an elastic-perfectly plastic formulation. The hydrodynamic behavior of materials is modeled via the gamma law and Mie-Gruneisen equations of state.
