Original abstract
This work deals with fractographical analysis of fish-eye crack formation under multiaxial fatigue. In this work, it is shown that the subsurface fish-eye type crack formation is the typical fatigue crack initiation mechanism in nitrided steels and the mechanism of subsurface nucleation was studied. Dependence between type of loading characterized by loading ratio is the bending amplitude and is the torsion amplitude) or number of cycles to failure and geometrical characteristics of fish-eye crack was studied. Moreover, Stress intensity factors for fish-eye crack were assessed.
