Abstract
Vinyl rubber dummy skin used in the deformable featureless head form exhibits rate sensitivity. This rate sensitivity seems to play a significant role in the interior head impact evaluation. In order to characterize the rate dependency of dummy skin, a linear visco-elastic material law is developed in FCRASH. To validate this model, a number of hcadform drop tests and interior head impact events are simulated using FCRASH and results are compared with the test data. Evidently excellent agreement is achieved between the analyses and the test data.
