Abstract This paper analyses the effect of surface treatment on fretting fatigue
specimen by numerical simulations using Finite Element Analysis. The processed
specimen refers to artificially adding a cylindrical pit to its contact surface. Then,
the contact radius between the pad and the specimen is controlled by adjusting the
radius of the pit. The stress distribution and slip amplitude of the contact surface
under different contact geometries are compared. The critical plane approach is
used to predict the crack initiation life and to evaluate the effect of processed specimen on its fretting fatigue performance. Both crack initiation life and angle can… More >
