PROPAGATION OF COMPRESSIVE STRESSES THROUGH A PLASTICALLY DEFORMING MATERIAL

Abstract

The present report considers the application of this material description to those problems of impact and explosive phenomena in which planewave analyses are applicable. The material description is first used in a discussion of the shock conditions in the material and the continuous conditions behind a shock. The general problem of shock-wave interaction with the continuous motion behind a shock is then consideredAND A PARTICULAR APPROXIMATE METHOD OF TREATING THESE INTERACTIONS IS DERIVED. A numerical solution is obtained for the impact at a plane surface with a second body of the same material. The material selected is aluminum for which the required data are available. The calculations were carried out by a 7090 IBM digital computer and the results are given in graphical form. (Author)
