Bending Stress Analysis In Sheet Metal Forming Process

Abstract

The sheet metal forming process is a unique type of metal forming process which enables the deformation of metals that are less than 6mm in thickness. In our analysis, we considered three different materials i.e.Aluminium, Stainless steel and Carbon steel-1020- annealed, that undergoes Bending stress using V die. The analysis is carried out using Finite Element Analysis in ANSYS software. The Analysis aims to compare the three materials concerning Maximum Principal Stress in (Mpa), Maximum Normal stress in (Mpa), Equivalent stress in ( Mpa) and Maximum Principle Elastic strain as inputs and Ultimate Tensile strength (UTS), Yield as output while performing bending Process. The outcome of the study shows us that the Stainless steel exhibits Lower Maximum Normal stress and Maximum Principal stress than that of Carbon steel 1020 annealed, even requiring the lowest Stress to start deformation and the Highest stress to reach failure in comparison with the other two materials. It also has the highest Hardness value compared with the other two. Sothe Stainless steel is expected to show less UTS having less max normal and Principal stress than Carbon steel 1020 annealed, but it has high UTS. Hence it is best suited for these conditions and applications.
