HUMAN NECK FINITE ELEMENT MODEL DEVELOPMENT AND VALIDATION AGAINST ORIGINAL EXPERIMENTAL DATA

This study describes a Finite Element Model (FEM) of a human neck and undertakes the validation of an original model against experimental data that is recorded with a human volunteer. A successful temporal validation of the new model was obtained under lateral, rear, frontal and oblique impact in order to evaluate the model against existing data. New validation parameters are based on an experimental test proceeded in the frequency domain in order to extract the volunteer's Head-Neck system's modal characteristics. In depth validation of the head neck FEM is then performed by superposing the numerical and experimental frequency response function. It is noted that the temporal domain appears to not be accurate enough. The study proposes a neck model with improved biofidelity and geometry description, paying special attention to the retraction mode. The retraction mode is often masked in the temporal domain.
