Abstract

The fracture behaviour of a round pipe with a circular-arc circumferential notch is analysed in the case of tension and bending loading , by assuming that an elliptical-arc external surface crack exists at the notch root. The stress concentration factor (SCF) is determined through theoretical expressions and a finite element analysis. Then, the stress-intensity factor (SIF) along the surface crack front is computed for four values of the dimensionless notch radius. The effect of stress concentration is discussed for both thick- and thin-walled pipes.
