![]() In this paper the author deals with the notion that circumferential cracks are generally considered unacceptable. Structural and leakage integrity of tubes affected by circumferential crackingĭOE Office of Scientific and Technical Information (OSTI.GOV) A modification to the usual nondimensionalization expression used for surface flaws in flat plates was found to give correct trends for the hollow cylinder problem. In the hollow cylinders, the fatigue cracks were found to agree accurately with the shape of a transformed semiellipse. ![]() In the solid cylinders, the fatigue cracks were found to have a circular arc crack front with specific upper and lower limits to the arc radius. Growth behavior of surface cracks in the circumferential plane of solid and hollow cylindersĮxperiments were conducted to study the growth behavior of surface fatigue cracks in the circumferential plane of solid and hollow cylinders.
