In side-crash phenomena, finite element modeling is essential in investigating the occupant's post-impact dynamic behavior after contact with the door panels. A number of modifications have been made to the model described here based on combined simulation and experimental verifications of the dynamic and pseudo-static characteristics of different materials such as foam, damper and individual sub-assemblies. This report illustrates how the modified material and structural modeling of different components improve the accuracy of the overall dynamic behavior of the FEM model in simulating different HYGE experiments to speed up and optimize the vehicle design process. The rib-module drop test results with two different polypropylene pads clearly indicate the effect of the pad unloading characteristics on rib displacement.
