Abstract: | A head injury model consisting of the skull, the CSF, the brain and its partitioning membranes and the neck region is simulated
by considering its near actual geometry. Three-dimensional finite-element analysis is carried out to investigate the influence
of the partitioning membranes of the brain and the neck in head injury analysis through free-vibration analysis and transient
analysis. In free-vibration analysis, the first five modal frequencies are calculated, and in transient analysis intracranial
pressure and maximum shear stress in the brain are determined for a given occipital impact load. |
