Material Behavior for Modeling Bumper Impact 2004-01-0010

A RIM material was selected for the rear bumper fascia of the Ford GT. As part of its performance criteria, the rear bumper fascia is required to withstand a 1.5 mph corner pendulum impact without sustaining permanent damage. Finite element modeling of this component was undertaken to predict whether the designed bumper fascia would meet the impact criteria. The mechanical properties of the material were required as input to the model, including the yield point and a representation of high strain rate behavior. The paper will present the testing methodology, the determined dynamic yield point, and a material model incorporating strain-rate sensitivity.
