Sheet-metal forming simulations are made using a plane-stress yield function proposed by Ferron et al. for orthotropic sheets. Following the general method for the integration of rate-independent plasticity models, the yield function has been implemented in the implicit Abaqus=Standard ΓΏnite element

A new method to evaluate the amount of springback in sheet forming processes based on the explicit \_nite element method and the orthogonal regression analysis is presented in this paper[ To calculate springback accurately\ a simple but e}ective contact searching algorithm is described and Lagrangia
