Abstract:

The compounding technique of obtaining approximate solutions for stress intensity factors is applied to periodically stiffened sheets containing cracks. The basic compounding method requires a simple modification if the stiffener actually crosses the crack. Probable errors in compounded results are shown to be small a few per cent by comparing some compounded results with known results. The stress intensity factor is calculated for a crack located asymmetrically between stiffeners.
