Recently, a lot of work and interest have been devoted to the development of multiaxial fatigue parameters for fretting fatigue life prediction. In this study, the fretting fatigue life and critical location ware estimated and evaluated through the multiaxial fatigue theories in a cylinder-on-flat contact configuration for Cr-Mo steel, SCM420, the material commonly is used in gears of the automobile and rollers of the conveyor. The strain-life curve was obtained from fatigue test for SCM420. The Fretting fatigue life and critical location were estimated through stress distributions, SWT-parameters and FS-parameters obtained from FEA. This paper showed possibility of applying multi axial fatigue theories to fretting fatigue life prediction comparing predicted life with experimental results.
