There are few experimental data in literature relating to femur cross-section moments in full-scale PMHS pedestrian tests. However, these moments are used as injury criteria to evaluate pedestrian protection. This study aimed to provide this type of data. In previous studies by the authors, 15 post-mortem human subject (PMHS) were impacted by four different generic simplified vehicle bucks (two sedans, a SUV and a van). Each PMHS was instrumented with three mono-axis strain gauges on its right femur (impacted before the left femur). To derive the moments in the femur from these strain measurements, three-point bending tests were performed on the femurs isolated from the corresponding PMHS tested. The moment-strain relationship for each strain measurement location was then established for each femur. By applying these relationships to the strains measured in the full-scale PMHS tests, the corresponding cross-section moments on the femur were derived. Finally, by scaling these moments, biofidelity corridors were established for the 50th percentile male pedestrian in terms of upper, middle and lower cross-section moments in the femur, and for four vehicle profiles. These corridors will allow assessing biofidelity of human body models, physical dummies and lower extremity impactors.
