摘　　要：对模拟人颅脑的矢状面、冠状面光弹性模型，在５个不同位置分别施加相同的撞击载荷，获得了应力波在其中的传播和分布规律，给出了应力集中的部位及其数值，为分析颅脑损伤机理提供了若干实验依据。By means of the photoelastic models for the sagittal and coronary sections of human head, and for five different locations of impact to it, the propagation and distribution of stress waves, as well as the stress concentration patterns in human skull brain system during external impact are investigated. The experimental information is helpful for analyzing the mechanism of skull and brain injuries.
