The probe SIFS (K1) reports these values. The main fracture mechanism in this model is the crack tensile opening Mode 1, which calculates K I. 4 shows output requests and includes general stress and displacement contours as well as fatigue-specific probes. The Failure Criteria can also be set to the J-Integral method.įig. This calculation is done along the distributed crack front, and the distribution of Stress Intensity Factor will control the adapting crack front shape. The crack will propagate when the calculated Stress Intensity Factor, K exceeds the Fracture Toughness K c.
The Stress Intensity Factor method is selected in this case. The Pre-Meshed crack object is selected, the option to carry out a Static Fatigue analysis is chosen and the Critical Fracture Toughness is defined. SMART Crack Growth is selected, and the menu is shown in Fig.
