This paper is intended to perform finite element analysis by and study the severity of the injury with and without helmet and the impact absorbing polystyrene with different shear modulus. The Impact absorption tests (drop tests) at three different points on head form were performed. The work also compares the deformations, velocities of the head form, accelerations that are obtained during the drop test according on the head form with and without the helmet and protective padding (liner) of different mechanical properties. The work also shows the necessity of different materials with energy absorbing.
