Shot Peening DEM-FEM Simulation Considering Shot Stream Expansion, Peening Intensity and Target Materials

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. 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.
