- •
Effective CPZ can be regarded as FPZ in the analysis of Mode-I fatigue cracking.
- •
Relationship between LCF and FCG is developed considering crack closure.
- •
FCG model is proposed based on effective cyclic plastic field and LCF.
- •
Good agreement between predictions and experimental data is found.
