The stress intensity factors along the crack front are calculated for straight-fronted edge cracks in bars with circular cross-section subjected to tension or bending loading. The results are deduced by means of a three-dimensional finite element analysis and the stress field singular behaviour in t

A semicmpirical formula for the stress intensity factors for short cracks is presented. Once the crack has reached a critical depth, designated as aa, the notch has no effect on the crack tip stress field and the stress intensity factor for a smooth bar with crack depth (n + 4 is applicable, where d

The paper deals with the determination of analytical expressions for the mode III notch stress intensity factors for circumferentially-sharply-notched rounded bars under torsion loading, starting from the theoretical stress concentration factors of the corresponding notch problem. An exact, closed-
