Numerical simulation of residual stress field induced by shot peening

In order to study the influence of shot peening velocity and shot particle diameter on shot peening results, ABAQUS software was applied to numerically simulate the shot peening process with various shot peening velocity and various shot particle diameter, and analyze the influence of shot peening velocity and shot particle diameter on the distribution and depth displacement of the residual stress induced by shot peening. The results showed: with the raise in shot peening velocity, the maximum equivalent residual stress induced by shot peening increased, the maximum equivalent residual stress and the maximum displacement occurred in the peening center; with the raise in shot particle diameter, the maximum equivalent residual stress induced by shot peening increased, the maximum equivalent residual stress and the maximum displacement occurred in the peening center.
