Ductile fracture of low carbon structural steel (S235JR) at low initial stress triaxiality has been predicted using a method based on the Stress Modified Critical Strain (SMCS) criterion and the Gurson-Tvergaard-Needleman (GTN) material model. The influence of microdefects on the material strength has been taken into account. The investigations, including tensile tests, have been conducted for standard cylindrical unnotched tensile specimens at low triaxial stresses. An advanced finite element method has been used to determine several
SMCS model parameters.
