A series of 24 frontal head traumatic impacts on macaques carried out in the past were simulated with a validated finite element model of the specimens. From these simulations, brain tissue response and head accelerations were extracted. Based on the accelerations, global head injury criteria were calculated. Correlation between the brain tissue mechanical parameters, the global head injury criteria and the concussion scored in the experiments were analyzed. Based on this analysis, global head injury criteria that best correlate with concussion score for frontal impacts were identified and injury risk functions for brain tissue that can be used for human FE models are proposed. In addition, the new results were compared to a previous study based on simulations of 19 occipital head impacts from the same data source.
