One of the brain model used in this study was shaped actual human brain including the cerebral sulci, gyri and ventricles. The other was simple-shaped model removed those structures. Each model was exposed to angular acceleration by impactor collision causing 4500rad/s^2 peak rotational acceleration with 8ms pulse duration. After rotating 60 degree, two models were decelerated with 1500 rad/s^2 peak, 30ms duration. As the results of experiments, the maximum principal strain at the corpus callosum in real-shaped model was larger than the simple-shaped model. And the concentrations in base of the sulci were also observed in the real-shaped model. Therefore it was clarified that the brain shape such as the cerebral sulci and corpus callosum affect the strain distribution., 金沢大学高度モビリティ研究所 / 金沢大学理工研究域機械工学系}, pages = {77--81}, title = {脳ひずみ分布に対する形状因子の影響(頭部のモデル化と計測)}, year = {2010} }
