Shot peening is widely used to improve the fretting fatigue strength of critical surfaces. Fretting fatigue occurs in contacting parts that are subjected to fluctuating loads and sliding movements at the same time. This paper presents a sequential finite element simulation to investigate the shot peening effects on normal stress, shear stress, bulk stress and slip amplitude, which are considered to be the controlling parameters of fretting damage. The results demonstrated that among the modifications related to shot peening, compressive residual stress has a dominant effect on the fretting parameters.
Research highlights
► A novel sequential FE simulation was proposed to study fretting after shot peening.
► Shot peening has a clear beneficial effect on fretting behavior.
► Fretting behavior is most affected by SP residual stress.
