Aspects Regarding the Constitutive Equations for FEM Analysis of Advanced Metal Forming Processes
Keywords:
metal forming, constitutive equations, Forge3, dieless drawing
Abstract
The main aim of this paper is to review some different models, from simple to very complicated, for computing the changes in flow stress depending on the deformation conditions. Some of the models can be applied to cold forming and some to hot and warm forming. A finite element analysis (FEA) of the dieless drawing process was undertaken. The FEA simulation was carried out using Forge3, a FEA software, specifically produced for metal forming simulation. An axisymmetrical 3D geometric model of the tooling and billet was constructed for the analysis. The data obtained from the FE model included temperature, equivalent von Mises stress, equivalent strain and material deformation velocity.
