Fatigue life calculations of machine components in approach of stress, strain and energy

Ligaj B., Karolewska K.
pages 501 - 504, full text

The paper presents the experimental verification of fatigue life calculation in the conditions of programmable loads. 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.
