Abstract

Abstract

The ballistic characteristics of the projectile obliquely penetrating into the concrete target were investigated, with such data as the penetration depth, crater depth and diameter, deflection angle obtained via the experiments and simulation calculation. The results from simulation agree well with those from the experiments. The results show that the oblique angle has great influence on the crater zone. The greater the oblique angle, the greater the projectile's deflection; the greater the impact velocity, the less the influence of the ballistic deflection angle; and the ricochet occurs when the oblique angle increases to a certain degree. Thus the relationship was identified between the ricochet angle and the oblique angle and the penetration velocity.
