| 内容記述 | The purpose of this study is to clarify head injury mechanism such as diffused axonal injury (DAI) under rotational impact by experimenting with a head physical model having actual human shape. A head physical model constructed from individual medical images of a head was used for the experiments. The model consists of skull, CSF, falx and brain, which represents actual human head shape. The model was exposed to angular acceleration by impactor collision causing 4500 rad/s^2 peak rotational acceleration with 5ms pulse duration. After rotating 60°, the model was decelerated with 1000 rad/s^2 peak, 40ms duration. Deformation of the model was measured with full-field by using digital image correlation (DIC). Moreover, magnitude of deformation was determined by calculating maximum shear strain. As the results of experiments, shear strain concentration at the corpus callosum and shear strain communication to depth of brain were observed. The region observed this phenomenon corresponded to the region where DAI occurs most frequently in real accidents. Therefore, shear strain concentration at the corpus callosum and shear strain communication to depth of brain showed important phenomenon in head injury incidence under rotational impact. | |||||||||||||||||
