Abstract/Summary Shot peening is an effective life extension surface treatment process. In this study, experiments were performed to investigate whether shot peening could be used to recover the fatigue resistance of aluminium alloy 7050 that has experienced prior fatigue damage. The results showed that shot peening may be used for restoring the original fatigue life of the material, but the effectiveness strongly depends on the amount of prior damage (e.g. the crack depth of any cracks that have already formed) in the material. A numerical model was established and the effect of residual stress was incorporated into the model. The prediction by the model agreed well with the experimental results in terms of trend.
