摘要
A method is disclosed for estimating or predicting residual strains resulting from metal formation. The method includes determining parameters indicative of physical and spatial characteristics of elements representing a formed metal part. A maximum plastic strain resulting from the metal forming processes is then estimated, as a function of the physical and spatial characteristics of a first one of the elements and a subset of the elements.
