Study of influence of hit velocity on the anti-penetration behavior of nubbly corundum concrete

Nubbly corundum concrete is a new type defending material, whose anti-penetration characteristics can be affected by many factors. In this paper, the penetration of the nubbly corundum concrete by projectiles with different hit velocity is experimentally studied. The results indicate that the penetration depth does not increase with the increasing hit velocity, which is different from the phenomena of the penetration of concrete and rock. The main reason is that the projectiles are destructed and can not continue to penetrate. Moreover, the higher the hit velocity, the higher anti-penetration capability of the nubbly corundum concrete than that of common concrete or rock.
