The study deals with failure criteria for S235JR steel subjected to spatial stress states. The predictions were made using the modified Gurson–Tvergaard–Needleman (GTN) material model, which takes into account the effect of microstructural damage. The relationship between the material strength parameters and the microstructural changes caused by plastic deformation was established by analyzing the void volume fraction. The microstructural failure criteria determined for S235JR steel refer to the moment of decrease in strength and rupture.
