HYPERVELOCITY IMPACT PHENOMENA

Abstract

Hypervelocity projectiles, having a velocity of about 9.3 km/sec at impact and a nominal mass of 4 gm, were used in order to determine the spatial distribution of spall numbers and masses as well as the relationship between various parameters and spall particle size. The study consisted of impacts into three different thicknesses of three different target materials. The target thicknesses were 1/8 in, 1/2 in, and 2 in; the target materials were 2024-T3 aluminum, AZ31BH-24 magnesium, and 4130 steel. The spall particles were recovered from a target consisting of a stack of 1/2-inch thick fiberboard sheet; the witness target is located ten inches beyond the metal target.
