Resumen en inglés The aim of this paper is to evaluate forces and torques in flexible joints of a flexible multi-body system (FMS). To represent such a FMS a 2D non-linear model based on finite element method is built. Its numerical form solution based on a stable integration scheme and on the non-linear Newton-Raphson method is described. As the evaluation procedure first requires that some model physical properties are obtained as identified parameters, two procedures are used: direct and indirect identification. They are respectively based on dynamic equilibrium verification and on comparison between simulated and measured kinematics of the proposed model. The development of the two procedures and a performance comparison between them is carried out
