Finite element analysis of elliptic cup deep drawing of magnesium alloy sheet

Purpose: In magnesium alloy sheet products have been attracting more and more attention in recent years because of their application potentials as coverings of portable electrical devices and automotive panels. Thus this paper focus on the deep drawing process of magnesium alloy sheet. Design/methodology/approach: The FEM soft ware DEFORM-3D is used to investigate the mateial flow character during the elliptic cup deep drawing of magnesium alloy sheet at elevated temperatures. Findings: Investigate the effective stress and forming load under various process parameter conditions, including the profile radius of die, the clearance between die cavity and punch, the blank holding force and working temperature during the elliptic cup deep drawing of magnesium AZ31 alloy sheet. Research limitations/implications: The initial blank's shape design and forming limit analysis of the elliptic cup deep drawing of magnesium AZ31 alloy sheet will be continued for future research. Originality/value: The original value of this paper is the finite element method is used to investigate the material flow character, forming load, stress and strain distribution during the the elliptic cup deep drawing of magnesium alloy sheet at elevated temperatures.
