ABSTRACT Simulation models describing the fundamental processes taking place during a shot peening treatment are being proposed since the last four decades in order to investigate, understand, explain, and predict the correlation between the influencing factors of shot peening and the process results. This article provides a broad and extensive literature survey on simulation models of the shot peening process that have been developed and applied in the past decades and summarizes the knowledge that has been gained. The simulation models reviewed are subdivided into two main groups of models with different purposes. The first group of models deals with the dynamic shot behavior during shot peening or its related processes and is commonly known as Particle Dynamics Simulation. The second and largest group addresses the quantitative description and prediction of the deformation processes and the residual stress development during a single and/or multiple particle impact. This group of models can be separated in the analytical models, which are based on the fundamental approach of Hertz, and numerical models, such as the Finite-Element method, which has become the method of choice in recent years. KEY WORDS Literature Survey, Simulation, FEM, Particle Dynamics, Hertzian Pressure
