Abstract

Aimed at the influence laws and mechanism of the nose shapes of the rod penetrators on penetrating performance, the research on rod penetrators with different nose shape vertical penetrating was carried on. The results show that for the 4340 steel target, the nose shape of the penetrator has some influence on penetration depth if the incident velocity is rather small, but the optimal shape is semi-spherical rather than ogival or flat, however, if the incident velocity is big enough, the effect of nose shape on penetration efficiency is very little and which only has some influence on it in the cratering stage; For the concrete target, the nose shape has great influence on the penetration behavior and the penetration performance of the ogive-nose penetrator is distinctly better than the other two. The effect mechanism of which was also investigated.

Key words： mechanics of explosion; penetration; nose shape
