Comparison of Various Ductile Fracture Models and Their Fracture Envelopes
Original language description
For the best prediction of ductile fracture when complex loading is applied, it is necessary to calibrate and to use convenient ductile fracture model. Ductile fracture initiation is especially influenced by the shape of fracture envelope. Hence, such model should consider the dependence of the stress triaxiality and deviatoric state parameter to fracture strain. In this paper are presented shapes of fracture envelopes for various fracture models which were calibrated for the austenitic stainless steel.Firstly, the plasticity of given steel was investigated. Then, the calibration constants of selected ductile fracture models were identified using various specimens and experiments. Finally, the description of their suitability is discussed.
