Research of Fatigue Crack Growth Based on Critical Plane Method
Shanghai Maritime University, Shanghai, China
To precisely simulate the path of crack growth, a simulation of crack growth progress has been presented by using the redevelopment function of ANSYS APDL and introducing the random criterion of crack propagate directions with critical plane approach. Based on the C(T) specimen test, extract the stress fields of crack tips, and set reasonable simulation parameters to verify the simulation method. The result shows that the initiation site and propagation path of crack are basically anastomoses to the results of test, which make a guiding function for preventing the accidents of crack growth and making anti crack plan.
Key words: fatigue crack growth / critical plane approach / finite element / APDL redevelopment
