Abstract
The high-velocity impact of a projectile with a stationary structure will lead to the catastrophic fragmentation of the projectile and some portion of the structure during the interaction. The characteristic size and velocity of fragments and the thermodynamic state of fragment debris are directly linked to the intensity of the impact-induced shock waves. Compressional or elastic potential energy introduced by the shock wave is converted to divergent kinetic energy as waves rebound from free surfaces. The magnitude of this kinetic energy determines fragment sizes and velocities. Entropy production during the shock-compression process, on the other hand, leads to elevated temperatures upon shock release, resulting in high-temperature solid, liquid, and liquid-vapor fragment debris.
