Abstract

Abstract

Monolithic and three-layered plates were normally impacted by hemispherically-nosed projectiles.The residual velocity-the initial velocity curves of the projectiles and ballisitic limit velocities were constructed.The penetration process of metal plates impacted by rod projectiles has been studied with numerical simulation code ABAQUS/EXPLICIT.The validation of models and parameters of materials has been proved by comparing the experiment results with numerical simulations.We investigated the influence of combination configuration of target on the ballistic characteristic, including the ballistic resistance and failure models.Furthermore, the impact process was also analyzed.The results indicated that the ballistic limit velocity of multi-layered plate was higher than that of monolithic plate.The dominant failure model of monolithic plate was shearing, but the dominant failure models of multi-layered plate were global dishing and local bulging.Moreover, the failure models of plates of multi-layered plates were in relation to their order in targets.
