In this paper, 3D dynamic FEM analyses with a precise model of human head by voxel approach were conducted. The model has 1.22 million parallelepiped elements with 10 anatomical tissues such as a scalp, CSF, a skull, a brain, dura mater and so on. To verify the validity of the model, an analysis on the cadavaric experiments by Nahum was done and it is confirmed that the model gives good agreement with these experiments. A front and rear impact analyses were also performed to investigate the relationship between the impact direction and the positions of the high measurement of pressure and stresses in the brain. The obtained result showed that brain injury has a closer relation with the equivalent stresses rather than the pressure.
