3-D Finite Element Model for Analysis in the Maxilla and Zygomatic Bones 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. This paper proposes finite element model of maxilla bone, left and right zygomatic bones impact for further analysis of effect of punch on the human skull. The finite element model is three-dimensional which solid Lagrangian elements and the explicit dynamics simulations were used for analysis. The human skull model used in this study was validated from the previous study. A foreign object impact generated contact force was used via load curve and initial velocity to estimate the contact force between the object and impacted bones. The impact force and stress distributions on the bones have been evaluated. The prediction of the bones response to the strike can be achieved using ANSYS LS-DYNA solver.
