Arrays of radial cracks are sometimes observed at the bore of pressurised cylinders. The stress intensity factors of closely spaced regular arrays of edge cracks depends primarily on the crack spacing and are approximately proportional to the square root of crack spacing for crack length to spacing ratios down to 0.16. A stress intensity factor expression for this range of spacing ratios and of engineering accuracy has been developed for a large regular array of radial cracks at the bore of a pressurised cylinde. For smaller spacing ratios the stress intensity factor depends on crack length than crack spacing and a complementary expression has been developed.
