Abstract

As for long-rod penetrator vertically penetrating semi-infinite target, the principal influence factors on penetration efficiency were analyzed in theory, and the influence rules and the influence mechanisms of them on the normalized penetration depth were discussed. The influence rules of the factors such as cross-section shape, nose shape, aspect ratio, density ratio between penetrator and target, incident velocity, Poisson's ratio, strength of penetrator and target on the penetrating process and terminal penetration efficiency were obtained. These can provide a reference for optimization design of long-rod projectile, protective armor and defense works.

Key words： penetration mechanics; long-rod projectile; penetration rule; semi-infinite target; design of rod penetrator
