THEORETICAL AND EXPERIMENTAL STUDY OF LOW-VELOCITY PENETRATION PHENOMENA PHASES I AND II

Abstract

Phase I has consisted of a literature survey to determine the state of the art. The results are summarized and a bibliography is included. It is concluded that semi-empirical correlation formulae and over-simplified theories do not give the results needed for armor design and are inadequate as a guide to understanding low-velocity impact phenomena. Phase II has consisted of the development of a new method of describing the elasto-plastic behavior of a material under impact conditions. The non-linear differential equations involved are expressed in a tensor formulation particularly suitable for computer calculations. The method used is very general and allows a wide variety of boundary conditions and material properties to be used. The work is described and the results of preliminary calculations are presented in this report.
