The translational acceleration concussions damages, such like the cerebral coup and contre-coup side damages, are reported in a traffic accident and crash contacts of human bodies in sports activities. The comparisons with the conventional HIC criterion and experiments by developed FE evaluation technique of Finite element evaluation algorithms are newly developed based on Gross's cavitation theory. It shows 100kPa for a damage criterion. In this paper the hydrostatic pressure criterion was verified through FE analyses propagation at the time of the head collision based on cavitation theory of Gross et al. The verification experiment by FEM analysis and the artificial head model are conducted, In experiments, PVC skull and gelatin brain are used to model the human head.
