Finite Element Analysis of an Aluminium Alloy Sheet in a V-Die Punch Mechanism Considering Spring-Back Effect

摘要

Sheet metal parts are used to manufacture a wide range of products. Bending and cutting the sheets into appropriate shapes by means of the physical process of shearing is the very first step in forming such a part. The current work is an attempt to provide the readers with an appropriate understanding regarding the deformation behavior of an aluminium alloy sheet by performing the finite element analysis (FEM) for two distinct die angles. The metal sheet is analyzed before fatigue failure and with the help of a software based analysis; the paper explores the phenomena of spring-back, associated with the metal sheet during its deformation, while subjected to the set of V-die punch, designed with suitable dimensions. The V-die punch as well as the alloy sheet is modeled in Solidworks 13.0 and their dimensions have been taken from practical standards. Finite element analysis for the same is carried out in ANSYS Workbench 16.0.
