Fretting Fatigue of Slot-dovetail in Turbo-generator Rotor Shaft

724 Fretting Fatigue Behavior with Double Contact Pads in A2024-T4 Aluminum Alloy

“…It can also be observed that the reduction of strength in fretting fatigue with double contact pads compared to single contact pad is significant when the gap between double contact pads is small. It has been reported that fretting fatigue strength decreases significantly with decreasing pad-to-pad clearance [3] On the contrast, the reduction in fretting fatigue strength is not signMcant, ifthe gap between double contact pads is…”
