Domozhirov, N. Makhutov] Conclusions: 1. The dependence of the fatigue crack propagation rate on the length of the plastic zone at the crack tip and the more accurate estimates of the size of this zone were used as a basis to propose a model for calculating the CGR which takes into account the effect of the variation of the yield limit of the material on the surface layer on the propagation of short fatigue cracks. 2. The following data are essential for application of the model: coefficients C and m of Paris's equations, the yield limit of the material on the surface, and the thickness of the surface layer with a reduced yield limit. 3. The model predicts an anomalously higher rate of crack propagation in the surface layer of the solid and also at stress intensity factors lower than the threshold Kth. 4. The special features of fatigue crack propagation in the surface layer of the solid with reduced yielding resistance of the material are determined by the combined effect of a reduction of the size of the plastic zone of the crack tip and an increase of the coefficient C1 in the exponential equation (3) on the crack propagation rate.
