A combined low‐ and high‐cycle life prediction model considering the closure effect of micro‐defects

In this study, a combined low‐ and high‐cycle fatigue (CCF) life prediction model, which considers the crack closure effect (CCE) of micro‐defects, is proposed based on the continuous damage mechanics. The model is decomposed into three submodels: the low‐cycle fatigue (LCF), high‐cycle fatigue (HCF...
