Abstract

Abstract

In this paper, we numerically studied the ballistic resistance of the metal perforated armor to the high-velocity projectile, and analyzed in detail the effects of various factors on its ballistic resistance, including the impact velocity, the oblique angle, the hitting location and the size of holes.The results showed that the effect of hitting position decreases with the increase of the impact velocity near the ballistic limit.Both the normal impact at the asymmetric hitting position and the oblique impact at the symmetric hitting position result in the projectile yaw.The residual velocity of the projectile and the penetration depth decrease dramatically as the oblique angle is larger than 45°, and furthermore, the ricochet appears as the oblique angle is larger than 65°.
