The purpose of this paper is to propose a set of frontal biofidelity corridors for the thorax in frontal impact. The corridors have been developed by biomechanical experts from several organizations including CEESAR, EEVC, Ford Motor Company, Humanetics, G.M Company, IFSTTAR, JAMA, JARI, LTU, LAB, PDB, UVa, and VRTC. The experts agreed on a complete process including the identification of the PMHS tests appropriate for biofidelity target definition and the data processing resulting in corridors. Impactor test: the Kroell tests series dataset have been reanalyzed and expanded with recent impactor tests. Two new force- deflection impactor corridors are then proposed. The total deflection is used rather than the skeletal deflection. In addition, based on the Kent et al. 2004 muscle tensing study, it was decided not to perform any force shift to the corridors. Sled tests with 3 point belt restraint corridors: the 8 PMHS tests described in Shaw et al. 2009 have been used to develop shoulder belt load versus time corridors and skeletal 3D deflection versus time corridors at 5 different locations on the thorax. Table Top test: no corridor but the relative reaction Force value at 20% of thoracic compression was proposed as biofidelity targets using the Kent et al. 2004 series, which gathers four different types of loading.
