【Abstract】

<正>Based on the damage experiment of projectile penetration into high-strength concrete target by using one-stage light gas gun,the macro-damage relationship between penetration angle of target and hit velocity of projectile is obtained as the penetration angle at 0°,10°,20°.Meanwhile,the damage morphology of target in pre and post experiment is characterized by the CT technique.The results showed that,as the angle changes from 0°to 20°,the penetration depth and diameter have a decreasing trend under the same hit velocity;as the hit velocity increasing,the penetration depth and diameter have an increasing trend on the same penetration angle. CT images can not only reflect internal structure of target,but also reflect internal damage after penetration.It is further proved that the CT technology is reliable on studying the penetration destruction and damage morphology of target.
