| Abstract | This paper studies the effects of stress ratio R on crack growth rate and fatigue strength for high cycle and very-high-cycle fatigue of metallic materials. First, the effect of R on fatigue crack growth rate is analyzed, and the result shows that the effect of R on crack growth rate at near-threshold region and on Paris region is well expressed by a unified relation. Then, a model is developed for describing the fatigue crack growth rate with the effect of R in near-threshold region and Paris region. The model is verified by experimental data of metallic materials in literature. Finally, a formula is derived for the effect of R on fatigue strength. The estimated results are in good agreement with the experimental data for high cycle and very-high-cycle fatigue regime in literature. The comparison of the present result with Goodman diagram is also discussed. (C) 2013 Elsevier Ltd. All rights reserved. |
