Abstract
This paper deals with the problem of mixed mode fracture. Elastic finite element analyses are described for circular rings containing a V-notch on the internal radius. The circular rings are subjected to a pair of unsymmetrical loads on the outside radius. With elastic analysis, the mixed mode stress field near the notch root is calculated. The analyses include calculations of the stress intensity factors for mode I and mode II, and of the strain energy release rate for co-planar crack extension. With the maximum circumferential stress method and the virtual crack extension method, the relationships between the angle of the first or the second kinked cracks, and the angle of loading are obtained.
