Increasing values of the parameter of loading-cycle asymmetry cause a shift of fatigue curves towards higher values of fatigue strength, which was quanti-tatively described by Walker in the high-cycle region. The aim of the presented paper consists in deriving the relations describing the shift of fatigue curves also in the low-cycle region where the shift is usually smaller than that in the high-cycle region and all low-cycle fatigue curves for various parameters of cycle asymmetry converge on the one value of ultimate tensile strength. Two new relations are derived and successfully verified in the paper.
