Abstrakt: The article suggests a method of determining the parameters of the equation of the fatigue curve taking into account the effect of the frequency and asymmetry of the load cycles. The dependences of the parameters of the equation on the coefficient of asymmetry of the load cycles are established. The article demonstrates the efficiency of the suggested method of predicting endurance of smooth specimens and of specimens with stress raisers on larger bases of low-frequency loading from the results of high-frequency tests by comparing a large amount of experimental investigations of the fatigue limit of the alloys AMg6N, ÉP202, and VNS-25 with calculated data.
