| Abstract: | 3 points bending specimen with a crack was taken as research object. Theoretical result of stress intensity factor was done by hand calculation firstly. Then according to documentation of ABAQUS software, different crack front modeling methods were used to do the fracture analysis under static loading. Stress intensity factors were calculated in both simulation methods. Comparison and discussion of stress intensity factor between theoretical and both analytical results were made in the end. |
