Analysis of Stress and Prediction of the Defects of an Ankle Prosthesis Using the Autodesk Inventor Software

摘要

The paper presents stress analysis of an ankle prosthesis and the prediction of the cracks appearance that may occur using the finite element method. The first test was performed using as material for the ankle prosthesis simulation, aluminium alloy 6061, and in the second test were use titanium as the simulation material. Von Mises's basic concept, failure theory, is also analysed, using Autodesk Inventor simulation software, in an attempt to give a perspective on the material from which the ankle prosthesis must be made. In conclusions were presented results for stress, endurance, and safety factors for simulated prosthesis.
