S235JR steel - Opis:
- 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) crite- rion and the Gurson-Tvergaard-Needleman (GTN) material model. The influence of micro- defects 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.
