    摘要: A method of predicting distortion in a workpiece may include measuring residual stress induced in a coupon surface of a plate coupon by a selected manufacturing operation. The induced residual stress measurements may be fitted to a curve shape function. A moment coefficient may be calculated based upon the fitted induced residual stress measurements. The moment coefficient may be used to calibrate a stress function and corresponding stress magnitude. The calibrated stress function may be applied to a model of the workpiece such that the distortion of the workpiece may be predicted.
