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.
