Finite Element Simulation and Experimental Studies on Projectile Perforation of Circular and Rectangular Plates

Abstract

Experiments and simulations on projectile impact to circular and rectangular plates made of aluminum alloy 2024-T3 were carried out. Ballistic limit and deformation of circular plates and rectangular plates at impact point were examined. The experimental results were compared with the simulation ones which calculated using the materials properties experimentally obtained. The effects of mesh size and fracture strain on both the crack limit velocity and the perforate limit velocity were discussed.
