Abstract
In this paper a numerical study of the ballistic performance of multi-layered metallic plates is presented. Monolithic, double- and triple-layered plates made of either steel or a combination of steel and aluminium, impacted by a deformable projectile in the velocity range of 750-950 m/s were studied. Finite element models were developed using the explicit code LS-DYNA. It was found that monolithic plates have a better ballistic performance than that of multi-layered plates made with the same material. It was also found that double-layered plates with a thin front plate of aluminium and thick back steel plate exhibit greater resistance than multi-layered steel plates. These predictions indicate that multi-layered targets using different metallic materials should be investigated for improved ballistic performance and weight-savings.
