The influence of coverage ratio on the residual stress and mechanical properties of a material is investigated by the finite element simulations of the shot-peening models of single shot impact and multiple impingement. For the single shot impact model, the equivalent plastic strain increases with the increase of peening frequency, but the residual stress is not significantly affected by the frequency, and therefore the material is strengthened by the peening frequency. For the multiple impingement model, the residual stress amplitude increases as the 100% coverage ratio is taken into account, and the equivalent plastic strain is similar with that in the single shot impact simulation. The experimental results of a stainless steel demonstrate that the combination of the two models is suitable for analyzing shot-peening process.
