We propose that by incorporatingstrain rate effects, critical plane approximation parameters can be effectivelyused to estimate fatigue life under various test conditions. Unlike the classicalapproach, this improvement offers the advantage of building the parameter versuslife relationship, regardless of the type of test used for calibration. To definethis new relationship, we present a calibration strategy that considers criticalplane models based on the Fatemi-Socie and Smith-Watson-Topper criteria. Theaccuracy of the method is verified using data sets extracted from the literature.A study on the impact of the stress ratio on the parameter versus life curve isincluded, indicating that although the relationships obtained depend on the valueof the stress ratio (R) used in the calibration, the life predictions derived fromthese relationships are statistically similar. life paramater critical plane Full Text Supplementary Files Nomenclature.docx Table.xlsx Cite Share Download PDF Status: Posted Version 1 posted You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
