This study aimed to develop a biofidel head-neck FE model comprised of scalp, skull, CSF, brain, dura mater, pia mater, cervical vertebrae and discs, 14 ligaments, and 42 neck muscles. We assessed the geometrical accuracies of all model structures. The model was validated by replicating three experimental studies: NBDL's high acceleration profile, Zhang's linear and rotational acceleration profiles, and Nahum's impact study. The results showed reasonable geometrical fidelity. The intracranial pressure and brain stress data of our head-only model (excluded neck structures and constrained the base of the skull) were similar to Nahum's and Zhang's reported results. As neck structures were not considered in Nahum's and Zhang's studies, the FE results of our head-neck model showed slight discrepancies. Notably, the addition of neck structures (head-neck model) reduced brain stress-strain values and uncovered the brain's intracranial pressure dynamics, which the head-only model failed to capture. Nevertheless, the FE simulation results showed a good agreement (r > 0.97) between the kinematic responses of our head-neck model and NBDL's experimental results. Therefore, the developed head-neck model can be used as a computational tool for an accurate and comprehensive understanding of the brain injury mechanism in various head impact scenarios.
