Description	Increasing the mean stress of loading cycle causes a shift of fatigue (Wöhler s or S-N) curves towards higher values of fatigue strength if the curves are represented by the upper stress of loading cycle in dependence on the number of cycles to fracture. A successful quantitative description of the shift in gigh-cycle region was published by Walker. The aim of the present paper consists in deriving relations that describe the shift of fatigue curves in the whole cycle region from UTS to permanent fatigue limit. Their applicability is demonstrated by successful fit of the family of tfatigue curves loading cycle asymetries when the curves are described by the Stromeyer qquation as well as by the Kohout and Vechet qquation. Also the limitation of Walker s approach in the case of high mean stresses is discussed and a certain solution is proposed.
