Abstract

Constitutive-microdamage equations are developed that are capable of simulating thermo-mechanical material behavior following high shock compression, dilatation, microdamage evolution and fracture, caused by projectile-target impact at hypervelocity. 1 Introduction Impact at hypervelocity of a target plate by a projectile can cause various types of damage, e.g. cratering and spall fractures, fragmentation of projectile and the impact area of the target, and formation of high velocity debris clouds that may include melting and vaporization of projectile and target materials [1-5]. The most dominant of the factors that determine the damage outcome are the impact velocity, the ratio of the projectile diameter to thickness of the target, and the thermomecha
