Abstract
With wars and the rise of the killings taking place in the world it was necessary for us as engineers and researchers that we step even slightest reduction in killings, and the current research is an attempt in this direction. Composite ballistic body armor materials has become a better body armor protection when contrasted with conventional steel body armor as far as its diminishment in weight and a perfection in ballistic resistance, in any case, the unpredictable reaction of composite materials combined with high expenses and restricted measure of information from ballistic testing has lead to modeling and simulation of ballistic body armor with different grade of material becomes the best option to optimize and design the composite body armor with less weight and affordable cost. The study aimed to develop domestic knowledge, model and simulate capability of composite armors compare it with other material at same weight about (0.75 kg). As a research, methodology there was modeling and simulation by ANSYS 14 Explicit Dynamic. Were used to model and simulate the bullet resistant body armor. The material used for modeling are stainless steel 304, Kevlar fibers with epoxy and composite system which consist of multi layers of different materials, and the weapon type used is assault rifle wz. 96 “BERYL”. It was used three velocities (800, 1000 and 1200 m/s) for projectile bullet. The simulation result shows that no completely penetration through the modeled composite system body armor and it has owned a high-performance compared with the other materials
