COMPARISON OF EXPERIMENTAL AND PREDICTED AXIAL PRESSURE VARIATION FOR METALLIC TARGETS IMPACTED BY METALLIC SPHERES

Abstract

Sufficient experimental data have been collected for five different cases of high velocity metallic impact so that the axial shock pressure variation can be traced in a semi-infinite target. The metals utilized were aluminum alloys and copper. In all cases, a spherical projectile was fired into a target plate of similar material. The aft spall velocity of the target plate was measured by means of a high-speed framing camera, and the shock pressure at the axial location in a semi-infinite target corresponding to the target plate thickness was computed from this spall velocity. These data are compared with the results of various theoretical methods for predicting the shock pressure variation in simi-infinite targets. The present data are also compared with other available experimental data.
