Abstract
This research investigated the factors influencing the penetrating resistance of the armor surface using the finite element method. In this study, firing tests on actual bulletproof armor and finite element simulation modeling of bulletproof armor using the SolidWorks program were compared. The pattern model of firing onto armor was created and simulated using the ANSYS Explicit Dynamic program. The damage test was conducted in accordance with the National Institute of Justice Level 3 standards. The bullet material used in the model was 7.62 mm tungsten carbide (WC) moved at speed of 847+ 9.1 m/s. In this simulation, two different kinds of bulletproof armor were used: SKD1 and Aluminum AL7075. According to the simulations, the armor plates were stacked with thicknesses of 6, 8, and 10 mm, and the angles of firing of bulletproof armor were at 0, 30, and 45 degrees. The simulation findings showed that factors influencing the considerable resistance of the armor plates to bullet penetration are increases in firing angle and armor thickness.
