Numerical simulation of impact effects during helmet - Hard obstacle collision

Abstract

This paper presents a simulation model of absorption effects during helmet collision with a hard obstacle.lt is based on a necessity to predict undesired consequences that may occur in case of helemet colision and impact with a hard obstacle. The primary aim of the paper is to determine real deformations during helmet collision with a hard obstacle by method of simulation of energy absorption effects and to establish a successfull model of optimum helmet design, from the aspect of engineering purposes, which corresponds to helmet behaviour in real conditions. Finite elements of the thin laminar shell type are used in helmet discretisation. Boundary conditions and loads are applied in such a way to simulate impact in the most realistic way.
