FEM model an effective tool to evaluate von mises stresses in shoulder joint and muscles for adduction and abduction.

摘要

Shoulder is one of the most complicated and critical joint. It consists of the clavicle, scapula and humerus. Studying individual functions of these structures is nearly unfeasible. In order to understand these relationships during different shoulder exercise, an attempt has been made to model, simulate and analyze the shoulder joint. The technique described in this paper utilizes the advanced 3D scanning; Computer Aided Design (CAD), DMU Kinematics Tool in CATIA V5 then Finite Element Analysis (FEA) to detect the stress points of the shoulder joints during adduction and abduction. FEM of the ligaments and the muscles are carried out using the hexa-penta mesh elements in Hyper Mesh and von mises stresses are analysed by LS DYNA software. The results for abduction and adduction are plotted and validated with the previous research papers as well as the limiting values of the different shoulder muscle for the range of motion 0° to 30°.
