A Formulation of Hydrodynamic Flow with Materials that Exhibit Elastic Plastic Behavior - The SMITE Code.

Abstract

This report describes a new formulation for an elastic-perfectly plastic computer code. The formulation uses a second order accurate integration method for numerically solving the governing partial differential equations. The algorithm uses an individual Eulerian grid for each material domain. These domains, which may be elastic, elastic-perfectly plastic, or purely hydrodynamic, are allowed to move freely through these grids communicating with each other through common interfaces; it is clear then that the boundaries of the domains are explicitly computed as part of the algorithm.
