Abstract
The objective of this study is to discuss a mechanism of the skull fracture of head injuries due to impact with finite element (FE) analysis and to develop the stress-based head injury incidence boundary. We previously reported the necessity of high shape fidelity head FE models to detect the possibility of fracture on the skull. In simulations using the FE head model (Titech model) which previously was constructed and has been validated, the head model impacted to a rigid plate model with springs where the head injuries could occur. The compression stress on the skull was distributed concentrically around the impact area. The maximum of the compression principal stresses on the outer table in every simulation, which were the largest among these bones, were plotted against the duration time of the stress. We developed the curve connecting a set of the average points in each simulation as the head injury incidence boundary. A simulation considering the fracture of the skull was thought to validate this curve.
