PENETRATION EROSION PHENOMENOLOGY

Penetration experiments of one-third scale tungsten alloy projectiles, with aspect ratios of 15 and 30 were performed in armor-like steel ta rgets for impact velocities between 0.8 and 1.8 km/s. Post-test flash radiographs show that portions of the penetration channel are filled w ith the erosion products from the projectile. The erosion phenomenolog y of long-rod tungsten alloy penetrators was deduced by sectioning pen etration channels and examining metallographic sections. Copyright (C) 1996 Elsevier Science Ltd.
