Numerical study of the behavior of magnesium alloy AM50 in tensile and torsional loadings

In this work, a numerical simulation of the behavior of the magnesium alloy AM50 in tension and torsion is performed. Preliminary experimental procedures were carried out in order to determine the material characteristics and the stress–strain response. Based on the experimental data, three material models were developed: linear elastic with isotropic plasticity, linear elastic with Johnson–Cook hardening and the Ramberg–Osgood model and their accuracy and computational time were investigated.
