✦ Synopsis

The compounding methods for calculating stress-intensity factors for complex geometrical configurations are reexamined. It is shown that techniques which were developed specifically for problems involving localized loads, e.g. a pin-loaded hole with a crack at its edge, can also be used when the loading is remote from the crack. When these techniques are used for cracks at unloaded holes, and for cracks in stiffened sheets, the compounding equations are as simple as those derived previously. However, fewer additional calculations are now needed and numerical tests show that there is no loss of accuracy. These advantages make the new procedures preferable to those used in the earlier compounding method.
