Shot peening is a cold working manufacturing process designed to induce residual stresses in the surface of the treated material. Theoretical and experimental studies have demonstrated the beneficial effects of shot peening on the fatigue resistance of materials that is a result of the layer of compressive stresses produced in the treated material. Many published studies have used finite element analysis modeling of the peening process to investigate the effects of various peening input parameters on the depth and magnitude of this compressive layer. In the current study, the LS-DYNA code is used to perform 3D dynamic finite element analyses of multiple cast steel high hardness shots impacting a titanium target in an overlapping manner. In contrast to other published analyses, the current work investigates combinations of peening process parameters and their effects on residual stresses. In addition, the current study includes design of experiments to develop regression equations to predict surface stress, maximum residual stress, depth of the maximum residual stress, and the zero-crossing depth using combinations of the peening process input parameters which are shot size, shot velocity, and shot impact angle. Finite element analyses for several different shot peening input parameters are then used in a comparison of results with the regression equations to assess their applicability.
