Analysing the Validity of a Skull Fracture Energy Criterion through Subject‐Specific Finite Element Modelling of Skull Impacts
Though numerous studies have investigated the mechanics and characteristics of skull fracture resulting from blunt head impacts, a criterion for skull fracture occurrence is still under discussion. proposed that the strain energy absorbed by the skull could be a good predictor for skull fractures. Multiple authors have attempted to validate such an energy criterion using finite element head models and experiments. However, current generic finite element models are unable to accurately visualize bone fracture initiation and propagation, which complicates the investigation of skull fracture. This study aims to investigate the energy criterion using subject‐specific head models, focusing on the inter‐subjective geometrical and bone material differences. The research group previously investigated the existence of an energy failure criterion with a double pendulum set‐up in a series of intact PMHS heads [5‐6]. For the experimental conditions of this study, skulls fail at a level of 7‐18 J for frontal impacts and 3‐23 J for temporal impacts. This study aims to critically investigate the energy criterion using 18 subject‐specific head models (three frontal, five occipital and ten temporo‐parietal) corresponding to the aforementioned experiment, focusing on the inter‐subjective geometrical and bone material differences.
