Surface Roughness and Residual Stresses on the Fatigue Life of Shot Peened Components: Theoretical Determination
The effects of the shot peening process on the fatigue damage are analysed and modelled. Surface roughness is modelled in a way that would increase the far-field stress.

| Sumario: | The effects of the shot peening process on the fatigue damage are analysed and modelled. Surface roughness is modelled in a way that would increase the far-field stress. Compressive residual stresses translated as closure stresses which tend to reduce the application of the far-field stress by introducing this closure stress on the crack flanks and thus the propagation of the crack is expected to be somewhat reduced compared to the unpeened condition. |
