Abstract

The penetration of penetrator with nylon-filled enhanced lateral efficiency (for short PELE) against 4340 steel plate at the speed of 1200m/s was simulated by LS-DYNA finite element software, and the influence on the ratio of length to diameter for generation of lateral efficiency was acquired. The result shows when ratio of length to diameter is comparatively small, the whole penetrator basically produces lateral efficiency; While remnant speed after penetrating target is small; When ratio of length to diameter is larger comparatively, part of penetrator produces lateral efficiency while remnant speed after penetrating target relatively is larger. Take validity of lateral efficiency and influence factors into account,4:1~6:1 is suitable for PELE of the ratio of length to diameter.

Key words： penetration mechanics; lateral efficiency; penetrator with enhanced lateral efficiency; computer simulation; ratio of length to diameter
