A computational method based on the membrane theory for the analysis of axisymmetric sheet metal forming processes such as punch stretching, deep drawing and hydroforming is presented. The elastic-plastic finite element approach is based on the flow rule associated with Hill's quadratic yield criter
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
