AB The issues present during simulations of the upsetting process of magnesium alloy Mg4AlZn are presented in this paper. The bar buckling, which is the main phenomenon limiting this process, was analyzed. The aim of the analysis was determining such conditions of simulations which would allow to obtain shape and eccentricity similarity to the real product. Two ways of buckling imposing in a theoretical model underwent research: non-axial movement and inclination of the upsetting tool working surface. The conducted analysis allowed to estimate the effectiveness of both analyzed ways of obtaining similarity between the theoretical model and the real process.
