Stress Intensity Factors for Cracks in Stiffened Sheets

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.
