This paper proposes a modification on SWT model concerning the prediction on fretting fatigue life, in order to take into account the material deviation from the ideal elastic-plastic behaviour, the so-called “Bauschinger effect”. The possible consequences of the Bauschinger effect on fretting fatigue life and mainly in fretting fatigue initiation are discussed. It is proved that Bauschinger parameter incorporated into the SWT model substantially improves the fretting fatigue predictions.
