The Particle Dynamics of Target Penetration
Abstract
New approaches are proposed for describing some of the principle features of target penetration by a projectile in the ordnance velocity range. These features include the following observed facts: (1) curved trajectories including the possibilities of perforation, embedment or ricochet, (2) loss of mass by erosion, and (3) breakup of the projectile into sizable pieces. Each of the approaches proposed is illustrated by examples. In addition, a considerable amount of literature on the subject is reviewed in order to place these new approaches in context. After providing historical background on his topic, the author develops and illustrates his basic ideas concerning a constant mass penetrator. He then extends the theory to the case of a variable mass penetrator, and considers a model of projectile breakup.
