Simulation-Based Stress Analysis for a 3D Modeled Humerus-Prosthesis Assembly

The development of mechanical models of the humerus-prosthesis assembly represent a solution for analyzing the behavior of prosthesis devices under different conditions; some of these behaviors are impossible to reproduce in vivo due to the irreversible phenomenon that can occur. This paper presents a versatile model of the humerus-prosthesis assembly. The model is used for stress analysis and displacement distributions under different configurations that correspond to possible in vivo implementations later on. A 3D scanner was used to obtain the virtual model of the humerus bone. The endoprosthesis was designed using 3D modeling software and the humerus-prosthesis assembly was analyzed using Finite Element Analysis software.
