The present research aims at obtaining a theoretical solution on basis of actural measurements of residual stress by shot peening. Firstly, it was conducted that residual stress on two different strength of plate specimens have been shot peened are measured by X-ray difractometer and the effect of a few type of shot peening conditions on profiles are confirmed. The equation to simulate profiles was obtained by the superpostition method of simple three stress, based on the equation that Y.F.Al-Obaid suggested. It was confirmed that the predicted stress profile shows good correspondence with experimental value in case of every shot peening conditions in this study.
