scope:
This Case presents an alternative procedure for calculating applied stress intensity factors during normal operation and pressure test conditions. The procedure is based on the principles of linear elastic fracture mechanics. At each location being investigated a maximum postulated defect is assumed, and the mode I stress intensity factor K1 is produced by each of the specified pressure and thermal loadings. Different procedures are recommended for axial and circumferential weld orientations.
