Development of finite element model for analysis in the realistic human skull impact

Concussion or head impact involves the brain injury from mild to severe. Most of the brain injury mechanism and brain lesions can be investigated from medical imaging. Alternatively, finite element model (FE model) of head impact is used for simulation and analyzing the brain concussion. Although a number of head impact models have been designed, they are still not be realistic. This paper proposes development of finite element model of the more realistic skull impact for further analysis of effect of punch on the human head. The finite element model is three-dimensional which solid Lagrangian elements and the explicit dynamics simulations were used for analysis. The foreign object impact generated contact force was used via load curve and initial velocity to estimate the contact force between the object and skull. The stress distribution on the skull has been evaluated. The prediction of the human head response to the strike can be achieved using ANSYS LS-Dyna solver. The simulation results were compared with the experimental data published by others for validation FE model.
