Abstract

The main goal of this research is to create a new ballistic helmet concept able to defeat high velocity rifle bullets, specifically the 7.62 x 39 M43 round. The current design consists of four layers, where the first layer is responsible for the deformation and breaking up of the projectile, the second layer for stopping the projectile, the third layer for reducing the back face deformation, and the fourth and last layer for absorbing the shock wave send into the helmet shell, next to the back face deflection of the latter. Whereas previous research gave possible solutions for the first three layers, this work focuses on the feasibility of the fourth, shock-Absorbing layer. A finite element model approach was used to see the influence of the shock-Absorbing layer on the risk on behind-helmet blunt trauma and to determine a suitable standoff based on a maximum force injury criterion.
