Recent Advances in Impact Dynamics of Engineering Structures - 1989,

Abstract

In this paper, a simple theoretical analysis of an old problem is presented. The analysis is more complete than earlier versions, but retains the mathematical simplicity of the earlier versions. The major thrust is to separate the material response into two phases. The first phase is dominated by strain rate effects and has a variable plastic wave speed. The second phase is dominated by strain hardening effects and has a constant plastic wave speed. Estimates for dynamic yield stress, strain, strain-rate, and plastic wave speed during both phases are given. Comparisons with several experiments on OFHC copper are included.
