Coupled thermomechanical finite element analysis to improve press formability for camera shape using AZ31B magnesium alloy sheet

Article

Abstract

In this study, a finite element analysis aimed at predicting and improving the press formability for a camera casing made of AZ31B magnesium alloy sheet was conducted. First, stress-strain curves and forming limit curves (FLDs) for warm temperatures were obtained. The data from these curves and the ductile fracture criterion of FLDs were then input into ABAQUS/Explicit finite element code to predict the failure occurrence of the camera casing. In the finite element method (FEM) simulation, for investigating the effect of reduced temperature during the punch cooling process on the formability of the camera casing, coupled thermomechanical computational modeling was considered and verified by comparison with experimental results. Based on the good agreement between the simulation and the experimental results, three parameters-blank holding force, elevated temperature, and friction coefficient-were selected to improve the press formability of the camera casing in the coupling of the FEM simulations and Taguchi’s orthogonal array experiment. The optimum simulation case was confirmed through an experiment.
