We performed a shot peening test and used a 2-D finite element model which predicts the compressive residual stress distribution below the material’s surface. In this study, the concept of ‘impact cycle’ is introduced to account for the irregularity in the shot’s impact position during testing. The impact cycle was imbedded in the finite element model. In the shot peening test, shot bombarded a type-A Almen strip surface with different impact velocities. To verify the proposed finite element model, we compared the deformed cross sectional shape of the Almen strips with the shapes computed by the proposed finite element model. Good agreement was noted between measurements and the finite element model predictions. With the verified finite element model, a series of finite element simulations was conducted to compute the residual stress distribution below the material’s surface and the characteristics of these distributions are discussed.
