| Abstract: | The application of the French lines to the prediction of high-cycle fatigue life according to the time of initiation of a macrocrack is justified. The French line is regarded as a line separating the regions of propagating and nonpropagating fatigue cracks. A method for the evaluation of the French line parameters in the region of low-cycle loading via the parameters of the Coffin-Manson diagram is proposed.Translated from Problemy Prochnosti, No. 1, pp. 88–95, January–February, 2005. |
