Abstract

Technique for modeling of stable fatigue crack growth has been developed which are based on the theory of local high-energy- type fracture mechanism acting at a crack front in the second stage of fatigue crack kinetics. The technique has been verified with the use of 3D finite element modeling and microfractographic reconstitution of fatigue crack growth.
