Current manikin testing and accident investigations may be inadequate to fully assess the potential for human injury in novel aircraft and automobile dynamic situations. An injury assessment system is needed that will relate manikin-based loading information to specific human injury predictions injury type, severity, and probability. This system may consist of an instrumented manikin, manikin to uman correlations, and a human injury criterion. The principal objective of this Phase I Small Business Innovative Research SBIR program was to develop the injury criterion for the human neck in axial compression. To develop the criterion, injury-producing situations from military mishaps were reviewed from literature, military databases, and individual Air Force mishap records. Neck-injury producing loads from approximately 35 experimental references were collected. A branched structure was developed to relate loading inputs primary and off-axis loading directions, loading magnitude, and subject history to injury outputs injury mechanism, injury severity, injury location, and experimental references. This branched structure can be applied to other loading directions and other body segments and allows each criterion to be readily updated as new experimental and injury information becomes available.
