The Current State of the Human Head Finite Element Modelling

Accurate human head surrogates and relevant injury assessment are needed for both head injury prediction and head protection system optimizations. Using a human head finite element model (FEM) is a proposed alternative method to head injury criterion for assessing head injury risk. The authors propose, for the first time, after a detailed literature review on head FEMs, a benchmark procedure in order to evaluate a model's ability to predict brain pressure, displacements and skull force deflections. To evaluate the ability of six FEMs to predict a set of measured responses obtained under published post mortem human surrogate impact conditions, a statistical method has been used. The author's main conclusion is that finite element modeling is a good head injury risk assessment method. Some lesions could be predicted by all FEMs, and it will be possible in the near future to define new head injury criteria based on numerical head models.
