Summary

In this paper, thermal deep-drawing process of extruded magnesium alloy (AZ31B) sheet was simulated by explicit finite element method using DYNAFORM. The forming temperature was at 300 °C. The variation in blank thickness was analyzed. The process defects such as wrinkling and localized thinning were predicted to demonstrate and optimize the corresponding experimental technical parameters. To improve the accuracy of numerical simulation, the blank mesh in finite element model was modified and divided into three regions. The region contacting with the punch-nose was meshed with finer elements. The simulation results showed that the thinning rate near punch radius of the blank reached the maximum value. So strength of this zone was the weakest in that of the whole workpiece. The deformed workpieces had apparent anisotropic distortion behavior in the flange, resulting from different material characteristics along different directions of the extruded sheet. All the results derived from the numerical simulations showed good agreement with the corresponding experimental results.
