โœฆ Synopsis

Al&met-This paper presents the boundary element method (BEM) and weight function method (WFM) to calculate the axial stress intensity factor as a function of crack depth for an externally flawed autof~t~g~ cylinder using the superposition principle. The axial stress Beids in an autofrettaged cylinder in which the mater&I model has both strain hardening and the Bauschinger effect are investigated. Good agreement is obtained b+tweeu the BEM and WFM over the range of crack depths 0 Q c/W < 0.75, where c is the crack Iength and W is the wail thickness width.

By means of the weight functions method stress intensity factors were calculated for axial semi-elliptical surface cracks in a pipe with cladding. The component is loaded by a thermoshock. Starting from a stress-free state the inner surface of the cladding is suddenly cooled down. The time-dependent
