Modelisation du mouvement du corps humain par la methode des elements finis.

Abstract

The behavior analysis of the human body various members is very complicated view to the complexity of its members and its various movements following the different planes and axes which governed it. Therefore, in biomechanical the human body modeling using the finite element method is essential and frequently used for the analysis of the various members of the human body in its static, dynamic, and during their movement. The members are often modeled by elements bars or beams, while the joints are considered as nodes. This will allow the biomechanics to obtain indications on the possible changes in order to improve the performance of the qualities of the prosthesis at level joints and constituent materials of the members. In our work, the modeling is based on the assembly of the upper and lower limbs of the human body separately statically and during their movement which is represented by the movement of the arm and the hip respectively. Also a three-dimensional modeling was carried out and the state of stress and deformation of the various members has been analyzed. Furthermore, and during the real movement of these members, the change of angles is often negligible and a kinematic and dynamic analysis of the members was released where the position of speed and acceleration have been determined.
