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