This paper deals with the analysis of plastic deformation and damage development in S235JRG2 steel in complex stress states and at different rates of loading. The material Gurson Tvergaard Needleman (GTN) model was applied. The analysis was performed for notched bars subjected to tension. An attempt was made to investigate the impact of load conditions on the value of critical void volume fraction (fc) in the GTN model. Numerical computations carried out with the use of GTN model made it possible to identify the sites of ductile fracture initiation.
