Validation is a critical step in finite element model (FEM) development. This study focuses on the validation of the Global Human Body Models Consortium full body average male occupant FEM in five localized loading regimes—a chest impact, a shoulder impact, a thoracoabdominal impact, an abdominal impact, and a pelvic impact. Force and deflection outputs from the model were compared to experimental traces and corridors scaled to the 50th percentile male. Predicted fractures and injury severity measures were compared to evaluate the model’s injury prediction capabilities. The methods of ISO/TS 18571 were used to quantitatively assess the fit of model outputs to experimental force and deflection traces. The model produced peak chest, shoulder, thoracoabdominal, abdominal, and pelvis forces of 4.8, 3.3, 4.5, 5.1, and 13.0 kN compared to 4.3, 3.2, 4.0, 4.0, and 10.3 kN in the experiments, respectively. The model predicted rib and pelvic fractures related to Abbreviated Injury Scale scores within the ranges found experimentally all cases except the abdominal impact. ISO/TS 18571 scores for the impacts studied had a mean score of 0.73 with a range of 0.57–0.83. Well-validated FEMs are important tools used by engineers in advancing occupant safety.
