A new neck was developed for the THOR-AV 5th percentile female dummy. The neck design followed the same concept as the THOR-AV 50th percentile male neck design and complied with the 5th percentile female neck anthropometry specifications. Prototype necks were built for biofidelity evaluations in six test conditions, covering the frontal, lateral, oblique and torsion responses. The neck frontal response has BioRank scores of 1.26 and 1.60 for Thunnissen et al. and Kang et al. test conditions respectively, both corresponding to good biofidelity. The neck lateral response has a BioRank scores of 2.39 and 1.65 for Wismans et al. and Kang et al. test conditions, corresponding to marginal and good biofidelity respectively. The neck oblique and torsion responses both have a BioRank score of 2.77 and 2.08 respectively, corresponding to marginal biofidelity. The overall biofidelity of the neck is good with a BioRank score of 1.96.
