The shot peening process is known for the surface treatment of metallic components. The process is used to enhance surface strength and extend component fatigue life by introducing a compressive residual stress pattern in the surface layers of the component. Numerical simulation of the shot peening process is a tool that has been recently used to help control the process. The simulation helps in investigating the effects of the process parameters with an aim of attaining the optimum residual stress profile and maximum process gain. In this paper, elasto-plastic finite element simulation is used to perform this investigative analysis. The process parameters that are varied in this analysis are: the shot diameter, shot velocity, incidence angle and target material. The analysis is to be carried for three different materials, namely, steel, aluminum and titanium. An Explicit commercial finite element code (ABAQUS) is used to simulate the impact phenomenon. The results of the analysis are sets of varying plots of residual stress through the depth of the targets.
