Engineering Models of Ballistic Perforation at High Velocities.

Abstract

This report presents the results of ballistic tests consisting of 10 shots of long rod penetrators, made from SAE 4140 steel, on target plates: 50.8mm and 75.0mm thick RHA, and 133.5mm 5083 H-115 aluminum. Impact and residual velocities as well as residual length of the penetrator have been measured. The target plates were sectioned and etched around the perforation cavities and subjected to close inspection. Mechanical properties of penetrator and targets were measured and a split Hopkinson pressure bar arrangement has been set up. A new five stage engineering model of perforation of a metal target by a rigid projectile has been developed which does not rely on empirical factors. (Author)
