COLLISION AND PENETRATION OF RIGID SPHERICAL-NOSE RODS IN INFINITE COMPRESSIBLE METAL BODIES

This paper is concerned with the penetration of metal targets by rigid spherical-nose rods under high velocity impact. For this purpose, attention has been focused on compressible, elastic-perfectly plastic targets. Governing equations describing the behaviour of a target in elastic and plastic regions are developed and the results of 6061-T651 aluminum targets are compared with previously published experimental data.
