In the past, several crash test dummies were developed in order to measure forces acting on the human body during different loading conditions. However, they are limited in their biofidelity and their application type (frontal, lateral etc.). Recently, several numerical human models were developed. Their main advantage in comparison with dummies is the possibility to model the human structures with its mechanical properties. The aim of this study was to redefine the material properties of the ribcage of the Finite Element mid-size male HUMOS2 model in MADYMO in order to be able to predict fractures occurring under different conditions.
