An Orthogonal Grid Technique for Studying Internal Deformation and Energy Absorption in Target Penetration.

Abstract

An experimental technique was developed using a split target and internal grid to study material deformation and flow as a result of penetration. Data taken before and after impact show changes in hardness profiles and also the strain distribution within the target. Energy balances equations were developed and showed that over 90% of the incoming energy of the penetrator can be accounted for by the strain energy in the penetrator and target material.
