Abstract
In order to avoid expensive 3-D finite element calculations for predicting the initial necking and post-necking behaviour during sheet metal forming, an internal length scale is incorporated directly into the constitutive relation. Thereby it is possible to account for thickness effect during necking in a 2-D plane stress analysis. The applicability of this approach is demonstrated in a number of simple sheet metal forming processes.
