User's Manual for C-HEMP, A Two-Dimensional Wave Propagation Code. Volume 1. Description and Derivations of the Code.

Abstract

C-HEMP is a two-dimensional finite-difference computer program for treating stress waves propagation, in either planar or axisymmetric flow, caused by impacts or explosive detonation. It was designed, implemented, and tested at SRI International under a three-year contract for the U.S. Army Ballistic Research Laboratory to develop a computational model for armor penetration. The manual for the C-HEMP stress wave propagation code consists of two volumes. This first volume contains the descriptions and derivations of the code. Keywords: Two dimensional, Wave propagation code, Armor penetration, Explosive detonation, Computational model, Micromechanical model, Shear banding, Brittle fracture, Ductile fracture.
