Abstract
A rolling contact fatigue model, the algorithm of fatigue crack
path construction in a semi-infinite elastic isotropic plate being
the key element of this model, has been proposed. Step-by-step
calculation of the path and stress intensity factors (SIFs) along it
are carried out on the basis of the singular integral equations
method by using characteristics of cyclic crack extension resis-
tance of material.
As an example, the case of the edge crack propagation in a
plate by normal opening (mode I) or transverse shear (mode II)
mechanism, when contact forces under rolling are simulated by
the concentrated force, is numerically studied.
