Detailed Windscreen Model for Pedestrian Head Impact

Pedestrian head impacts on windscreen are a potential source of pedestrian injury and form part of the EuroNCAP Pedestrian Star Rating. Thus, there is a strong wish to increase pedestrian CAE predictive capability for windscreen impacts and hence create pedestrian safety measures early in the vehicle development cycle, rather than relying on expensive and time-consuming hardware testing. Existing CAE technology, because of the complex material behaviour involved, including fracture, did not enable realistic simulation of windscreen impact. This paper describes the development of new CAE techniques and more realistic material models for windscreens, in order to enable virtual development of protection measures to reduce pedestrian head impact injuries.
