Abstract
A method for predicting distortion and residual stress in a workpiece resulting from a peening process may include the steps of providing a coupon including residual stress induced in a coupon surface by the peening process, calculating a moment coefficient representative of residual stress induced in the coupon surface, calibrating a stress function to the moment coefficient, applying the stress function to a workpiece model of the workpiece, and computing at least one of predicted distortion and residual stress of the workpiece resulting from application of the calibrated stress function to the workpiece model.
