Based on these experimental observations Monte Carlo simulations of the corrosion fatigue process of different-sized specimens were conducted. The results of the simulations showed a good agreement with the experimental results. At a constant fatigue life ratio N/N_f, there was no specimen size dependence in the distribution of nondimensional crack lengths F(2l/d) and, at constant stress cycles, the distribution of crack lengths F(2l) is nearly constant regardless of the variations of the specimen diameters. Based on the above results, the simple estimation method of corrosion fatigue lives for the different-sized specimens was proposed. The estimated results give a good agreement with the experimental results.
