Abstract

ABSTRACT This paper presents approximate solutions to the dynamic response of three impulsively loaded structures: a wire with an impulsively loaded end mass, an impulsively loaded circular ring, and a cantilever beam with a tip mass subjected to an impulsive load at its tip. The material is assumed to be rigid, perfectly plastic with strain rate sensitivity. A proposed power law form of yield stress strain rate relationship is used to simplify the theoretical development. Numerical solutions are presented for mild steel and are compared with previously published results. Elastic effects and wave propogations are ignored.
