Title: Strength analysis of human skull on high speed impact
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.
