High frequency hammer peening is a recent improvement method which is probably one of the most effective for treating welded assemblies. The process applied in order to numerically estimate the effects of the treatment and to take into account the influence of its main parameters in order to optimize the treatment are presented in this article. These results were obtained in the scope of a study whose long-term aim is to propose an approach that can be industrially applicable for fatigue design of welded assemblies treated by high frequency hammer peening. The experimental study carried out in parallel is presented in the document IIW: XIII-2394-11.
