Dynamic Response of a Human Head to a Foreign Object Impact

This paper presents an analysis of a human head response to impact by a foreign object. The analysis is accomplished via an integration of a head-striker contact force function with a 3-D finite-element (FE) head model. The contact force function developed by the authors is used to estimate the contact force between the solid striker and the human head. An explicit FE solver, implemented with the contact force function, is employed to predict the human head response to the contact impact. The analysis is verified by comparing the present results with the experimental data published by others. Based on the present solution, the effects of the different impact conditions on the intracranial pressure of the head are investigated.
