Conference paper


An analysis, using the boundary integral method, was made of the plane problem of an edge crack under tension (Mode I) upon which a varying Hertzian stress field (Mode I plus Mode II) was superimposed, as in the inner race of a bearing of a high speed aircraft engine. Mode I, Mode II and effective stress intensity factors were computed and directions of crack propagation determined using both the maximum tangential stress and minimum strain energy density theories. Large discrepancies were found between the two theories. The curving of the crack out of its plane as it progresses was qualitatively shown. Further work in progress is described.
