Construction of probabilistic model on interior crack initiation and growth behaviors for high strength steels in very high cycle fatigue

In very high cycle fatigue for high strength steels, one can usually observe the fish-eye on the fracture surface and an inclusion is observed at the center of the fish-eye. The fine granular area (FGA) is also found in the vicinity around the inclusion at the crack initiation site on the fracture s...
