A non-linear viscoelastic model is introduced by employing a new formulation where the relaxation time of rate processes is directly dependent on the induced deformation state applied to the material. The plastic flow of amorphous polymers is considered as a continuous structural change, and the yie
## Abstract+onstitutive equations are derived for the nonlinear viscoelsstic behavior of amorphous glassy polymers in the subyield region, A polymer is thought of as an ensemble of cooperatively rearranged regions trapped in cages. In the phase space, a cage is modeled ss a potential well, where a
