This paper studies the impact of bullet with aluminum alloy plate fixed on all sides. Simulations were carried out to study effect of bullet impact angle and thickness of aluminium alloy plates. These simulations were performed using Finite Element Method implemented through Ansys Workbench. The target plate was struck at 0°, 15°, 30° and 45° obliquely and the impact velocity was 830 m/s in all tests...
This paper presents the numerical simulations to determine the impact resistance of Personal Armor System Ground Troops (PASGT) helmet. Initially impact of spherical projectile on PASGT helmet travelling at 205 m/s is studied. The result of this simulation was used to verify the material data and compare the work with previous literature. Two standard tests, namely the MIL-H-44099A and NIJ-STD-0106...
