Abstract

We study thermomechanical deformations of a thick elastic-viscoplastic target being penetrated by a rigid long cylindrical rod, and assume that target deformations as seen by an observer situated at the penetrator nose tip are steady. We presume that the target response can be adequately modeled by the Brown-Kim-Anand flow rule. We analyze the effect of different material parameters on the deformations of the target in order to elucidate their relative importance, and hence enumerate more critical ones. We also study the effect of the penetrator nose shape and the penetrator speed on the deformations of the target. © 1992.
