Plate Perforation

Abstract

The perforation of finite-thickness plates by rigid projectiles, are discussed here through analytical models and numerical simulations. The models consider the projectile’s non-constant deceleration during the perforation process, due to the effects of the front and back surfaces of the plate. These considerations are shown to account for many sets of empirical data for both metallic plates and concrete slabs. In particular, the models result in accurate predictions for the ballistic limit velocities of many projectile/plate combinations, and for the residual velocities of the projectile after plate perforation.
