Axisymmetric Penetration of Ceramic Plates by Tungsten Rods

Abstract

We study the effect of the impact speed of the tungsten rod on the axisymmetric deformations of an AD-85 ceramic plate. Tungsten is modeled as a linearly strain-hardening elastic-plastic material with the failure strain dependent upon the strain-rate. The ceramic is modeled as an elastic-plastic material with pressure cut-off. Effect of frictional force at the target/penetrator interface is accounted for, and failed elements are removed from the analysis. It is found that at the higher impact speeds, even tungsten particles at the impact end fail.
