Fretting fatigue life depends on the microscopic changes on fretting surface, fretting wear, and elastic-plastic deformation of specimen and contact pad. Therefore hybrid analysis of wear and contact stress will provide more accurate and practical predicted values of fretting fatigue life and fretting wear volume. Fretting wear test was carried out for different pad lengths and contact pressures using 3.5NiCrMoV rotor material. A method of predicting wear volume in fretting fatigue was proposed in terms of wear damage parameter obtained by elastic-plastic contact and wear analysis.
