Numerical Simulation of Magnesium Alloy AZ31B Sheets with Thermal Deep-Drawing Process

Abstract:

The finite element numerical simulation for the formability of magnesium alloy AZ31B sheets with thickness of 0.8mm and diameter of 140mm has been proceeded to investigate the formability using the current finite element software. Under the condition with blank holder force of 8KN and deep drawing speed of 0.3mm/s at 200
, the sytematic analysis and prediction of the thickness change and the forming rule for thesimulation process of the blank has been carried out. Under the same parameter, the drawing parts by deep drawing with a hydaulic machine were obtained and the thickness tested. It has been found that thickness change rules and the forming rules of the experimental results were in agreement with the numerical simulations.
