Introduction: Finite element (FE) simulation of shot peening has been widely applied to investigate the influence of the shot peening parameters on peening results like residual stresses and roughness [1-8]. Shot-shot interactions, shot-target interactions should both be considered in the shot peening simulation to yield physically realistic results. Discrete element model (DEM) - Finite element model (FEM)coupling methods have been shown to effectively predict the shot stream and shot peening effects by accounting for shot-shot and shot-target interactions [9, 10].
