Abstract

Stress intensity factors were calculated for partly circumferential surface cracks at the outside of a pipe. The pipe is loaded by internal pressure and by thermal stresses. The weight functions method is used to calculate averaged weighted stress intensity factors at the deepest point and at the surface points of the crack. The evaluation of temperatures and stresses in the pipe and the application of the weight functions method are described. Numerical results are given for an application to steam generator tubes.

By means of the finite element method crack opening displacements were calculated for long axial surface cracks at the outer wall of a pipe. The wall thickness to inner radius ratio of the pipe was 1 to 10. Following a procedure introduced be Mattheck et al. weight functions were evaluated by means

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
