Abstract

A coupled thermomechanical analysis of the Taylor impact test considering flat-ended cylindrical specimens of different materials fired at several striking velocities is presented. To this end, a large strain rate-dependent thermoelasto-plasticity model is used to define the constitutive relationships appearing in the momentum and energy equations both solved in the context of the finite element method. The influence of the strain, temperature, and strain rate effects on the material response is particularly analyzed. The numerical predictions are experimentally validated and compared with results provided by previously reported simulations and simplified analytical expressions. © 2002 American Institute of Physics.
