Abstract

This research has been carried out to identify the strongest and weakest part of the human skull on high speed impact condition by using finite element simulation approach. There are nine parts of skull model to be examined, i.e., frontal bone, front mandible, side mandible, maxilla, nasal bone, occipital bone, parietal bone, temporal bone and zygomatic bone. The parts are impacted by a small rigid ball at constant velocity of 20 m/s. Three dimensional Finite Element solver FEBio is employed to do the simulation. Four mechanical responses; acceleration, displacement, effective stress and effective strain are monitored after 1 ms the ball contacts with skull. When the response parameter shows the strongest part, it is scored 100 whereas the weakest the weakest is scored of 10. The total score from four parameters are then summed up. The results show the weakest among the cranial bones is the parietal bone. On the facial section, the front mandible and the nasal bone are the weakest parts among other facial bones.
