.... The Newtonian behavior of the polymer melt is modeled as rigid-viscoplastic medium. Standard finite element coupling is used to model the mutual metal–polymer interaction. The simulation results in the form of forming pressure profile, localized blank temperature profile, formed shape, and strain distribution...

...Z. Y. Jiang; A. K. Tieu, Mem. ASME Friction at the interfaces between two rolls and a strip being plastically deformed by the rolls is an important consideration in both theory and practice of metal forming. In this paper, a 3D rigid viscoplastic finite element method (FEM) was used to model...

..., employing a rate-independent elasto-plastic constitutive model combined with a fracture criterion which accounts for the complete loading history. In the present investigation this work is extended with respect to rate-dependence by employing an elasto-viscoplastic constitutive model in combination...
