In studying considered two different boundary conditions for human head impact response by using a finite element analysis(FEM). In tied condition all nodes are connected tightly and in slide condition relative displacement between two contact-faces are allowed in the direction of contact face. The three-dimensional finite element human head model constructed hexahedron solid elements based on MRI data to explain the mechanism of closed head impact injury. This investigation was to examine the boundary conditions of human head organization with validity of modeling. By this report, a procedure of constructing the model only with MRI data is reported and the results of both boundary conditions were compared with the impact experiment by acrylic cylindrical container and Nahum's cadaver experiment.
