Résumé / Abstract
The development of solid deformable contractile muscle models is an ongoing research in biomechanics. Conversely to multibody musculoskeletal models with 1D forces along the muscle lines of action, such models can compute the 3D forces in the muscle volume. Specifically, the transverse force transmitted between the muscles can be considered. A recent in vitro animal study revealed that the axial force (i.e., obtained by electro-stimulation) is dependent on the transverse forceapplied during the contraction [1]. The present study aims at evaluating this effect on the human thigh musculature. This in silico study compares the forces obtained in the different muscles for a given set of activations with and without introducing contact between the muscle surfaces.
