Popis:	Rotating bending fatigue tests were carried out in order to clarify the correlation between fatigue strengths of pit-type notched and circumferentially notched specimens of 0. 16% carbon steel. The obtained results show that the notch radir of the branch point ρ0 are almost the same and about 0.6mm in the two types of notched specimen. It is found that the fatigue strengths of the two types of specimen can be estimated on the basis of linear notch mechanics. Moreover, the master curves of Ktσw1 and Ktσw2 vs 1/ρ for the two types of specimen are equal. This implies that the fatigue strength of the specimen with a defect may be estimated from the fatigue strength of a circumferentially notched specimen.
