Modeling of ductile tearing for RAFM steel Eurofer97

Original language description

The contribution describes experiments and numerical modelling 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) andby 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.
