Abstract

A human body finite element (FE) model including discrete internal organs and whole body muscles was developed to elucidate injury mechanisms of occupant internal organs in real-world automotive accidents. The discrete internal organ models were validated against experimental test data using porcine specimens while the whole body FE model was validated against five cadaver test data on frontal impacts. In addition, the human FE model with and without a braced condition was applied to frontal impact analysis. Simulation results suggest that occupant postures could alter according to muscle activation level and have some effects on occupant internal organ injury mechanisms.
