Abstract

An investigation of the mechanical response of the human head subject to externally applied forces is analysed using the finite element method (FEM). The model's geometry description is based on individual 3D MRI datasets of the head. After segmentation the MRI data serves as input to a fully automated mesh generator. The underlying algorithms of the mesh generator are stable and fast. Isotropic and anisotropic meshes consisting of tetrahedra or brick elements are created with a predefined spatial resolution. The meshes are of high quality with regard to numerical stability of the FE calculation. Transient head impact simulations can be carried out on the basis of these meshes with a spatial resolution of up to 2 mm. The results of the impact simulations are validated against previously published experimental data obtained from cadaver tests.
