Finite element analysis of copper tube to study the behavior of equivalent strength during the severe plastic deformation process

Abstract

In this work, Finite Element Modeling is used to depict enhanced perception about the spd process. A 3-dimensional FE model was built to simulate the copper tube drawing process using Ansys2020R2 software. The severe plastic deformation (spd) process is used to manufacture high-precision tubes for different industrial applications. The finite element analysis for severe plastic deformation process suitable for sheet and solid is already done but numerical study to optimize the nanostructure tube yet not done. In this process, the tubes are drawn in a controlled fashion through a die to reduce their diameters and wall thickness. Modeling and simulation of metal forming processes are becoming increasingly popular, as the resulting models have shown to be useful tools for optimizing existing processes and developing new ones. In this paper, finite element analysis to depict the deformation, yield stress, ultimate tensile stress, and strain during the severe plastic deformation process is explained. In addition, the final dimension of a tube with very high precision is calculated after the first pass of the spd process. The von-mises stress observed is 381.31 Mpa. The tube thickness was reduced by 1.16 mm.
