In order to assess of accuracy of the calculations, the experimental research of the C45 steel were carried out under static load condition (R = -1), and under programmable loads. The research was realized under stress control condition. On the basis of obtained results, the fatigue life diagram in approach of stress (Sa-N), strain (eac-2Nf) and energy were (DWpl-N). A comparative analysis of calculation results with the results of experimental tests for two step loadings revealed a significant influence of the maximal stress values in the spectrum on fatigue life, for each of the applied calculation methods.
