Finite element analysis of single and double layered composite lamina for ballistic impact

On the field of battle, the protective gear plays a significant role for safety of personals. It is desirable that the gear protection level should be high and light weight, so that they can be carried easily. The aim of this study is to analyze, through simulation, the actual behavior of the impact of a 0.303 caliber bullet on the Kevlar-149 composite sheet for single and double layers using the finite element approach. The lamina of composite material Kevlar-149 and steel has been utilized for the bullet impact test using ANSYS software in order to determine the stress and strain in the lamina. The final analysis gives the maximum stress, strain, total velocity, total acceleration, total deformation and the directional deformation for the single-and double-layered composite lamina.
