Simulation and Test Validation of Windscreen Subject to Pedestrian Head Impact

Pedestrian head impact with windscreen is one of the major causes for pedestrian severe injury or fatality. A FE model is established with shell and solid elements representing different layers of a laminated windscreen. Major strain criterion is used to deal with the failure of windscreen. Simulation results are validated by Euro NCAP pedestrian head-to-windscreen impact tests. The results show that the FE modeling of windscreen can effectively predict the pedestrian head injury and the failure pattern of the windscreen. This method can be an effective tool for vehicle pedestrian safety evaluation and development.
