The objective of this study was to delineate the dynamic axial compressive responses of the Hybrid head-neck system and compare with the intact human cadaver head-neck complex responses. The Hybrid III head-neck preparation was tested under dynamic loading at rates to 8.0 m/sec. Inertially compensated forces, axial deformations, and distal generalized six-axis load cell histories were gathered at dynamic sampling rates. The localized axial compressions of the neck were obtained using retroreflective target information and high-speed photography. The Hybrid III dummy responded with non-linear and rate stiffening characteristics with minimal initial softening. This was in contrast to the human cadaver tissues wherein initial softening characteristics were present in the force-deformation curves. The Hybrid III neck was found to be at least two times stiffer compared to the human under dynamic axial compressive loading. Furthermore, the shape of the Hybrid III force-deformation response was different from the human cadaver tissues. These differences must be included to properly extrapolate the results from the Hybrid III to predict injury in real-world vehicular crash environments.
