The distribution and intensity of residual stresses due to shot-peening are dependent upon a lot of parameters; some of them are involved with the material characteristics, the other ones are relying upon the shot-peening process conditions. Preexisting stresses on the surface of the part in the initial state have no influence on final state after shot-peening; on the opposite stresses applied after shot-peening operation may alter for a large part the field of residual stresses. A theoretical approach has been developed and is conformable to experimental results.
