Tools and Methods for Analysis of Fatigue High-Cycle Stochastic Loading for Evaluating the Accuracy and Reliability of Numerical Solutions

The article presents methods of processing and the results of the analysis of the accuracy of solutions obtained when calculating the structure fatigue life in the case of random loading using domestic and foreign computer systems. Unlike foreign analogues, domestic software products for calculating the fatigue life of a product under random loading are based on the regulatory documents of the Russian Federation, which are proposed along with methods adopted abroad.
