[Regular Paper] Computational Modeling of Traumatic Brain Injury Due to Impact on Different Sides of Human Head

Abstract

Traumatic brain injury (TBI) is one of the most life-threatening injuries and a leading cause of the majority of disability and death across the world. Majority of the damages to the tissues are initiated by tensile and shearing structural failures. We report a three-dimensional finite element model of the human head where different parts are represented by appropriate material models. Simulations are performed for the case of dynamic loading on five locations of the head namely, frontal, frontal-top, parietal, occipital, and temporal. The developed model is validated with experimental literature. The distribution of intracranial pressure and von Mises stress is studied in detail. We observe that parietal bone is the strongest, and frontal-top concussions as more likely to result in loss of consciousness. In addition, the occipital impact represents the higher probability of neurological damage.
