Abstract:In this study, the constitutive equation of the high-strength Mg-Gd-Y-Zn-Zr alloy sheet was established by tensile tests at different temperatures and different tensile rates. The U-shape bending forming process of the sheet was simulated under different process conditions by the DEFORM software. The variation rules of the stress field, strain field and free bending force of the formed parts were analyzed, and the accuracy of the finite element simulation was verified by the U-shaped bending test. Studies have… Show more
