A model for the long-life fatigue behavior of small notches

The effect of notches and intrinsic defects on the long-life regime fatigue properties was studied. A crack-closure-at-a-notch (termed CCN) model for predicting the fatigue life and fatigue threshold stress was developed based on the assumption that the da/dN vs. $\Delta$K$\sb{\rm eff}$ relation is a unique material property independent of crack length. The variation of crack closure level with crack length for a crack emanating from a notch was found to depend on the material properties, the notch size, the notch acuity, and the applied load conditions.
