... The results showed that the fatigue life of the joints increases with increasing sheet thickness, but the fatigue life increase is limited. In all joints, fretting caused the initiation and propagation of fatigue cracks at the interfaces. Increasing sheet thickness can reduce the extent and degree of wear...
