THE EFFECTS OF SHOCKWAVE PROFILE SHAPE AND SHOCK OBLIQUITY ON SPALLATION: KINETIC AND STRESS-STATE EFFECTS ON DAMAGE EVOLUTION

Abstract

Shock‐loading of a material in contact with a high explosive (HE) experiences a “Taylor wave” (triangular wave) loading profile in contrast to the square‐wave loading profile imparted via the impact of a flyer plate. Detailed metallographic and microtextural analysis of the damage evolution in spalled Cu samples as a function of square/triangle and sweeping detonation‐wave loading is presented.
