Il'in, G. Karzov, V. Leonov] The article considers the possibility of using in practice the Socie-Morrow-Chen model for calculating the life of structural elements with stress raisers. It shows that there is good agreement of the theoretical estimates with the results of the experimental determination of the number of cycles corresponding to the initial stage of development of damage, NL. To develop the model the article suggests a procedure of taking into account the influence of the local mean stress of the strain cycle on NL, based on the use of a single dependence of the strain amplitude on the number of cycles up to the appearance of a crack with any coefficients of load cycle asymmetry R that takes into account the influence of R solely on the crack growth rate in the zone of stress concentration. The numerical calculations make it possible to establish the "effective” coefficients of reduction of fatigue strength which increase with an increase of the cyclic load base.
