In this study some material tests including tensile test and forming limit diagram (FLD) test are performed to evaluate the forming characteristics of the AZ31B magnesium alloy sheet and to construct a database of its material properties which can be used for various studies on this material. Tests are carried out at different temperatures and strain-rates, orientations of the specimens to rolling direction and gage lengths, showing the effect of these process variables on the material properties. Also the hardening behavior is inversely calibrated by iteratively performing numerical simulations for the simple tension tests until the numerical simulation results match well with experimental engineering stress curves.
