One, Two, and Three-Dimensional Impact Computations.

Abstract

A one-dimensional impact problem was run on a computer to determine the characteristics of the DORF-9 code. This code, in a two-dimensional, axisymmetric mode, was used to study the penetration of a 25.5-mm steel plate by a copper, shaped-charge jet, which was simulated by a 6-mm, semi-infinite, copper rod impacting normally on the plate at 7.5 km/s. This problem was also simulated by a plate-on-plate impact with the code operating in a two-dimensional, Cartesian mode. The thickness of the penetrator plate was varied. Penetration, hole growth and shape, shock-wave propagation, and spallation were compared for the rod and penetrator plates. The TRIDORF code was used in a three-dimensional, Cartesian mode to run a problem of a bar impacting on a plate. Comparisons were made between the rod and bar impacts. (Author)
