چکیده مقاله
In this study, the finite element method was used to simulate a three layer sandwich structure The numerical results are in good agreement with the experimental results The results of finite element analysis for different speeds were investigated and shown By increasing thespeed of the bullet and increasing its energy, the rate of degradation is increased and at high speeds the bullet can penetrate the structure by overcoming the top surface of the structure and by crossing the copper layer and causing the surface to become obscured Important pointin all impacts is to increase the structural rigidity until the stress value reaches its maximum
