Abstract

In this paper, oblique impact of ogive nose projectile on 5083-H116 aluminum alloy plates was numerically investigated. Three parameters such as impact velocity, impact angle and target configuration were varied to observe their influence on the ballistic resistance of targets. Based on the results, the oblique angle of impact acts an important role on the deformation mode of targets. The penetration of projectile dominates targets under low oblique angle impacts and the deformation changes from embedment to ricochet as oblique angle increases. Beside the oblique angle, the ballistic resistance of target is heavily dependent on impact velocity. Targets are perforated as impact velocity increases even if oblique angle becomes larger. Target configuration is another factor on the protective performance which is increased using thicker plates. The ballistic response of monolithic and double layer targets for the same thickness is very close each other.
