摘要：
Strain-power criterion of fatigue fracture initiation is formulated for bcc-metals, in particular, for perlitic steels on the base of some physical and mechanical ideas about damage cumulation under cyclic loading. Fatigue crack growth model which allow to describe the crack path and rate into inhomogeneous stress field at various stress ratio factors is proposed.
