The crack closure phenomenon significantly influences low cycle fatigue (LCF) crack growth. The crack closure theory deems that a crack can grow only when the applied load is greater than the fatigue crack opening and closing loads. The revised crack clo...

Many studies have shown that the linear elastic fracture mechanics (LEFM) method based on the stress intensity factor range (?K) has limitations that cannot be ignored. Due to neglecting the influence of plastic deformation near the crack tip, LEFM shows...
