A Study on a Simulation of a Head Form Impact Against Plastic Plates 922085

A Finite Element Method (FEM) simulation was conducted to predict energy-absorbing characteristics in an impact of a head form against plastic plates.Static and dynamic material tests were conducted in order to determine material properties of the plastics. The properties were applied in an explicit FEM code.The FEM results were validated through the impact tests by the head form against the same plastic plates. It was proved that the FEM could simulate the test result well, when the precise material properties were introduced in the simulation.The method can be expected to be available to predict energy-absorbing characteristics during the impact by the head form against automobile plastic components such as shell portions of instrument panels.
