Introduction
Shot peening, known for its potential to improve fatigue strength of metallic parts, can be seen as a multiple and progressively repeated elastic-plastic interaction between
the surface and the shots. With each impact the target undergoes local plastic deformation while the shot is moving into the material. After the contact between the target
and the shot has ceased, compressive residual stresses remain at the surface and small tensile residual stresses in the inside.
Developing a model to analyze the process of shot peening is useful for several reasons; to be able to predict the material state after peening without having to conduct
costly experiments and to be able to optimize peening processes. In contrast to prior studies found in the literature [1-4], a more detailed approach by simulating several
single impacts on a 3-dimensional surface is chosen to model the shot peening process.
