Numerical and Experimental Investigation of Electromagnetic Free Bulging of AZ31Magnesium Alloy Sheet
The electromagnetic free bulging experiment and the coupled-field numerical simulation of the EMF process were carried out to determine the possibility to improve the formability of magnesium alloy AZ31 sheets(1mm thick)at room temperature.Formability data were examined using strain measurements.The numerical simulation for the electromagnetic sheet free bulging is performed by means of ANSYS FEA software.Compared with quasi-static FLD results,increase in the major and minor principal strains of approximately 87%and 39%were achieved,respectively.The effects of various process parameters on electromagnetic bulging of AZ31 magnesium alloy sheets were evaluated.Three-dimensional(3D)FE model is established to predict the electromagnetic bulging of the sheet.The simulation results agreed well with experimental observations.
