Numerical study of the stress concentration factor in geometries of machine elements using Ansys® and Inventor®

Abstract

In the present study the stress concentration factor by the finite element method in a round bar grooved axially under tension, a stepped flat plate subjected to bending and a stepped round bar subjected to torsion can be found. The stress concentration factor was obtained in the simulation laboratory through the commercial software ANSYS Workbench® version 19 and Autodesk Inventor 2016® and they were compared with the experimental curves enunciated in Peterson book, finding similarities up to 0.02% between simulation and experimental methods; and 0.3% between both pieces of software.
