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
## Abstract A thermal model based on explicit time integration is developed and implemented into the explicit finite element code DYNA3D to model simultaneous forming and quenching of thinβwalled structures. A staggered approach is used for coupling the thermal and mechanical analysis, wherein each
