A new challenge in the DEM/FEM simulation of the shot peening process: The residual stress field at a sharp edge

Shot peening (SP) is used to enhance the fatigue life of metallic components. The knowledge of the resulting residual stress (RS) field in the vicinity of geometrical features working as stress raisers is essential to fully integrate SP into the design stage, but is of very difficult achievement, both from a numerical and experimental standpoint. Finite elements (FE) proved to be a powerful tool for tuning the SP process and predicting the RSs,...
