Analysis of Finite Element Models for Head Injury Investigation: Reconstruction of Four Real-World Impacts

To gain a better understanding of head injury biomechanics, advanced models of the head/brain complex have recently been developed. A lack of suitable real-world data to validate these models prompted the current study. The objective of this study was to reconstruct four real-world crashes with known head injury outcomes in a full-vehicle crash laboratory, simulate the head/brain responses using kinematics obtained during these reconstructions, and compare the results predicted by the models against the actual injuries sustained by the occupant. Cases where the occupant sustained no head injuries (AIS 0) and head injuries of severity AIS 4, AIS 5, and multiple head injuries were selected. The models used were the Wayne State University Head Injury Model (WSUHIM) and the NHTSA Simulated Injury Monitor (SIMon). Results showed that both models were able to predict varying injury severities consistent with the difference in AIS injury levels in the real-world cases.
