Abstract:  
Abstract The present paper is an attempt for set the basis for a realistic shot peening (SP) process simulation that will be capable to predict the corresponding products. The work is divided in three parts. The first part refers to the calculation of the realistic number of shots that impact to a representative area and the calculation of shot velocity and angle distribution as a function of shot peening process parameters via a kinematic simulation model. The second part includes the development of a numerical simulation model which is applied to investigate the shot interactions. The third part refers to the shot patterns generation by developing a Boolean model. Keywords Shot peening, stochastic modeling, finite element modeling, residual stress
