Methodological conditionings of a modified low cycle fatigue method of tempered 41Cr4 steel in comparison to some other materials

In the research work results of the application of modified LCF method in the assessment of fatigue parameters of various materials were discussed. The new software algorithm was proposed in the determination of fatigue parameters. A comparative verification of the new procedure with bibliographical data confirmed the possibility of the replacement of classical LCF by proposed original MLCF method as especially suitable test in the case of heterogeneous materials microstructure, particularly when it is hard to design Wohler’s diagrams as well as to carry on research according to the classical LCF method.
