Investigation of Helmet-Head Interaction in the Aspect of Craniocerebral Tissue Protection

The paper is focused on the problem of brain protection for the soldiers exposed to the effects of improvised explosive devices explosion under military vehicles. The soldier uniform predict the helmet whose main function is ballistic protection. In this article, the paddings mechanical properties were analyzed used in the helmet in context to brain protection against impact head inside the vehicle. As the paddings material the polyurethane foams with different density and mechanical properties were used. For finite element method analysis, a head with helmet model was created. The results suggest strong correlation between paddings characteristic and protection efficiency.
