In this study, the intracranial response and the cranial stress of a human head model obtained by FEM is verified in order to investigate the mechanism of brain contusion by comparing with the example of autopsy data. Although the finite element method is widely used for the head injury analysis in recent years, data used to verify the calculation result is few and only the limited data of the experimental result by using cadaver are referred. In this study autopsy data are used in order to obtain relation between input (impact speed, weight, etc) and output (pressure, stress, etc) statistically. First, three-dimensional head FE model including skull, cerebrospinal fluid, brain, was built from ach geometries obtained from CT and MRI images. Then, intracranial response in the model was calculated for the verification by LS-Dyna.
