A rotating disk of uniform thickness containing an internal symmetric crack at any position is treated as a plane problem of elasticity. The stress function is first assumed as a series form satisfying the traction-free condition of the crack edge. For the outer boundary, a modified boundary collocation method is applied. The outer boundary is divided into several segments, and the unknown coefficients in the assumed stress function are determined by modified boundary conditions based on the resultant force along each segment, together with the single-valuedness of displacements. Finally the stress intensity factors are calculated by the stress function obtained using a limiting procedure. Variation of the values of stress intensity factors with increasing numbers of boundary segments are examined, and the convergence seems excellent for a wide range of crack parameters. Various configurations with about forty segments were analyzed, and the results are summarized in tables and figures. A radial crack always gives a higher K-value than a tangential crack of the same size and eccentricity. The KⅡ-value of the latter is found to be small compared with the corresponding KⅠ-value. |
