A non-destructive method is proposed for estimating residual stress distribution in an object part due to shot peening. The method involves measuring the eigen strain distribution in a small test piece made of the same material and peened under the same shot peening conditions as the object part using the layer removal technique. The residual stress distribution in the part is calculated from this eigen strain. An experiment was carried out to estimate axisymmetric residual stresses in a shot peened cylinder. The results measured directly from the cylinder show good agreement with the results predicted by the proposed method.
