The HUMOS model, developed in the context of a European collaboration [1, 2], has been upgraded. The aim is to enhance the shoulder model biofidelity under lateral impact. First, modifications such as arms positioning and articulation modeling have been realised with the Radioss® (Mecalog) software. Secondly, the model was assessed using experimental data obtained at the LBMH [3, 4]. A comparison study of data provided by numerical simulations and experimental impacts was carried out. Main data analysed were deflections and impact contact force-time histories.
