| Abstract;The purpose of this study is to understand the effect of skull local shape on the peak stress and stress distribution. A skull-brain finite element model of the human head was constructed by the CT anatomy images. This model includes inner and outer tables (cortical bones), diploe (a cancellous bone), brain and celebral-spinal fluid (CSF) layer. The mechanical properties were obtained by the aid of the published data. The model was validated by using the three types of the published test data from cadaver experiments. In order to know the local shape effect, the present model was compared with the H-head model under impact. The load was applied to a freely supported head on the frontal bone in the midsagittal plane. The Von Mieses stress distributions of the cortical and the cancellous bone were different from each other. A head model with the shape of high fidelity is necessary in order to detect the possibility of the fracture of skull. (author abst.) |
