Abstract
This paper discusses analytical procedures for safety evaluation against fatigue failures initiated from surface planar flaws, which are considered the most harmful defects in real structures, such as pressure vessels and piping systems. Several numerical solutions are presented on fatigue crack growth from a surface flaw. Special attention is paid to the features of crack shape changes during growth. A simplified procedure is proposed, based on a comparison of experimental results and those adopted in the ASME Code, Sec. XI. The analyses used two sets of numerical results on stress intensity factors, one obtained by Kobayashi and the other by Raju and Newman.
