Originální abstrakt

The contribution describes experiments and numerical modeling performed to deal with ductile tearing for RAFM steel Eurofer97. Based on results of tensile testing and results of FEA, a micromechanical model of ductile fracture Gurson Tvergaard Needleman (GTN) was calibrated. This model was then applied for simulation of measured J R curve. To successfully simulate J R curve by GTN model, crack length increment was separated into increment created by crack tip blunting (stretch width zone increment) and by ductile tearing itself. J R curve corrected to crack tip blunting was satisfactory described by GTN model choosing suitable element size in the region of crack propagation.
