Abstract

Tissue-level brain injury criteria are essential for analyzing brain injuries using finite element head models (FEHMs), but their consistency remains unclear. This study applied the data-driven method previously proposed for maximum principal strain (MPS) injury criterion to determine thresholds for von Mises stress (VMS), pressure, maximum shear stress (MSS), and the rate of MPS. It then assessed the consistency of these criteria in terms of injury status, injury location, and injury overlap rate in 18 impact simulations. The results showed that the MPS, VMS, and MSS criteria had strong consistency, enhancing the utility of FEHMs in clinical brain injury analysis.
