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." . . . "6"^^ . "Hadraba, Hynek" . . . .
