PENETRATION AND CRATERING

E. Paul Palmer

Abstract

Abstract : Effects of target and projectile materials on crater volume, area and penetration are given and empirical impact laws derived. Preliminary measurements of subsurface flow and wave propagation and of surface flow in cratering are reported. Production of micron-sized spray particles with velocities to 25 km/sec is reported. Experiments on wave propagation in rods are outlined. Results of electric-arc-heated gun development are reported.
