Abstract
Starting from physical basis, a robust three-dimensional constitutive model for the finite strain response of amorphous polymers is briefly presented. This model accounts for the high strain rate and temperature effect. Intramolecular as well as intermolecular interactions under large elastic-inelastic behavior are considered for the mechanisms of deformation and hardening. In particular, it is found that the secondary relaxations of polymer chains play an important role in the deformation process for the high strain rates and low temperatures. For a wide range of temperature and strain rate, the proposed constitutive model has been validated in compression for three amorphous polymers: polymethylmethacrylate (PMMA), polycarbonate (PC) and polyamideimide (PAI).
