摘要：
The variation of the stress intensity factor along the front of an elastic bar of circular cross-section is determined. Both straight and circular-arc crack fronts are modelled using a three-dimensional finite element analysis of the tension and bending problems. Results are obtained for crack depth to bar diameter ratios ranging from 0. 1 to 0. 594, in the case of cracks with straight fronts, and from 0. 175 to 0. 6 in the case of cracks with curved fronts.
