Research on Protective Materials with Analysis of the Influence of Bulletproof Helmet Surface Curve on Bulletproof Performance
Abstract:
The deformation of the bullet non-penetrating the bulletproof helmet can cause a contact between the inside of the helmet and the head. This contact can cause injury to head. In order to study the non-penetrating phenomenon, the material of the bulletproof helmet are regarded as Johnson-Cook material model of ideal plasticity. The helmet surface curve is accurately drew by reference the national standard GA293-2012 "bulletproof police helmet and mask". The research use ABAQUS/Explicit to simulate 54 type pistol with 7.62mm bullet shooting helmet at a speed of 450m per second. The results show that shooting point further away from the top of a helmet, the more damage to head may be cause.
