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-0106.01 Type II helmet are also simulated. For the simulation on MIL-H-44099A, a fragment-simulating projectile (FSP) strikes the helmet with an impact velocity of 610 m/s. For the simulation on NIJ-STD-0106.01 Type II helmet, the projectile is a 9 mm full-jacketed bullet with a striking velocity of 358 m/s. Results from the simulation show that the KEVLARs helmet is able to resist a 9 mm full-jacketed bullet travelling at 358 m/s. The above simulations were performed using Finite Element Method in explicit formulation, implemented through Ansys AUTODYN-3D.
