Experimental Data for Characterizing Perforating Impacts: Fragmentation Processes

摘要

The impact of compact projectiles against plates has been investigated to improve the phenomenological description of the impact and perforation processes, especially at those speeds at which the projectile and target show significant breakup. This investigation identifies and characterizes the internal failure processes involved in perforation and fragmentation. It employs momentum and energy balances to characterize the dynamics of the system of fragments expelled following perforation.
