英文摘要In this study, based on the understanding of blunting and re-sharpening to micro-void coalescence mixed mechanism, a new full-stage fatigue crack growth model is proposed by exploiting the energy distribution concept. As the crack growth rate increases, the transformation efficiency of three types of mechanisms exhibited different trends. The parameter m in the Paris' law, derived from the new model, is in accordance with the experimental results. The new model is accurately verified by considering some engineering materials, including steels, titanium and aluminum alloys, which would be further applied to other innovative materials such as composites and high-entropy alloys.
