Abstract

In this paper, a trial test of projectile penetration through sand gravel-aluminum plate combined target is designed, and two kinds of gradation tests at different speeds are carried out. The whole shape of aluminum plate on the back of target, the high-speed photography of armour piercing process and strain response data at different positions of target plate are analyzed. The results show that at the same speed, the gradation is different and the size of opening is different, which indicates that the pebble grade pairing has certain influence on the damage degree of armor piercing. Under the same gradation, the higher the velocity of the projectile is, the bigger the loss of cobble is. Unlike the concrete continuous medium, in the process of penetrating gravel target plate, before and after the hole position will appear the pebble injection. This is due to the fluidity of the pebbles. The greater the velocity of the projectile, the larger the jet flow is.

Key words： aluminum plate-sand gravel combined target; armor penetration; gradation
