Finite element analysis of material and parameter effects in ballistic armors

Abstract

The literature about the ballistic armors are mostly focused on 2 or 3 different parameter effects. The aim of this study, differently, is to find and compare the effects of specific materials on protection of composite ballistic armor plates against high-velocity projectile impact. The effects of stacking sequence for different materials, projectile type, target plate shape and impact obliquity are investigated individually. It is shown that the proposed stacking sequence decelerates the residual velocity of the projectile better than the other considered arrangements. The average percentage of kinetic energy absorption of rectangular shaped Kevlar 29/epoxy plate is considerably higher than that of circular shaped Kevlar 29/epoxy plate.
