| Abstract | Constitutive models for glassy polymers have been based on the concept of a flow resistance internal variable for over 20 years. Through investigation and implementation of these state-of-the-art models, the current authors identified a new possibility for characterizing this class of polymers, which can simplify the analysis and frame them in a well posed family of constitutive models, especially suited for using the variational constitutive update approach. A visco-hyperelastic model is proposed which results in one single equation to be solved at each time step in the constitutive incremental update. Comparison against experimental data is performed and a numerical example inside a FEM framework is given. Mots clés — Glassy Polymers, Variational Updates , Finite Viscoelasticity. |
