A number of clavicle finite element (FE) models have been developed to study clavicle injuries in automotive side and frontal crashes. However, no loading response corridors exist in the literature for clavicle FE model validation. Therefore, the purpose of this study was to develop the clavicle response corridors for axial compression and three point bending, which were shown to represents the clavicle loading condition in side and frontal crashes respectively. Ten clavicles were loaded to failure in each of these two loading configurations at strain rates measured in sled tests. Both structural response (force VS deflection) and material response (force VS peak strain) corridors were developed for use in validating clavicle model loading response and injury prediction capacity. The method for creating both structural and material level corridors could be extended to develop corridors for other components of human body.
