Abstract
Based on the 3-D crack propagation analysis software named FRANC3D V6.0 and a finite element software, a finite element model of fracture mechanics was established by means of sub-model technique. The crack propagation of center hole of rotating plate was simulated. Little deviation of the computing results with the manual solution indicated the feasibility and accuracy of the method. The model was developed to predict the propagation life of disk containing cracks on the pin holes. The 3-D dynamic crack propagation of the model was simulated. The stress intensity factors and the propagation life of the disk were calculated. The analysis method is feasible. The most dangerous crack is on the surface of the pin hole of the disk.
