method for determining the fatigue notch-size-effect is presented based upon the development of closure in the wake of a newly formed crack growing from a notch. A comparison with experimental results is in accord with predictions. The effect of crack closure on the formation of non-propagating crac

A theoretical analysis is performed for the effect of strain hardening on fatigue crack closure in plane stress and plane strain conditions based on a modified strip yield model. It is shown that the effect of the strain hardening exponent n on the opening stress ratio is small, less than 1.3% in pl
Fatigue tests have been carried out on edge notched mild steel specimens of various thicknesses. Results are presented showing the effect of thickness on crack initiation, crack growth and the geometry and fractography of the fracture surface. It was found that both crack initiation and crack growth
