Analytical and experimental studies of the surface flaw

  • C. W. Smith
Symposium on the Surface Crack


This paper uses the Newman-Raju model, the Paris crack-growth-rate law and a fixedR ratio to demonstrate the analytical considerations associated with predicting stress-intensity distributions and fatigue crack growth of surface flaws under conditions of small-scale yielding. Subsequently, problems which lie outside the realm of the model used in the analytical description are presented. It is concluded that, while the model employed provides remarkable predictive capability in a variety of surface-flaw problems, many exceptional cases remain to be modeled.
