Summary

In order to evaluate a structural integrity of rotating machinary, a roter disk model specimen with an inner surface crack was used for rotating test and J-integral was calculated by the finite element method (FEM). This method can predict that stable crack growth occurs at a rotating speed in which the maximum value of the J-integral along the front of the surface crack becomes greater than the fracture toughness JIC of the disk material. In addition, Two-criteria method was applied to the assessment of rotor disk integrity. It was recognized that the critical speed from Two-criteria assessment agreed well with that from the JIC-criterion.
