Abstract

A theoretical structure is proposed to characterize the thermo-mechanical response of solid polymers at temperatures close to the glass transition. This structure is first developed in a one dimensional setting for shear, and constrained to satisfy the entropy production inequality. This results in expressions for shear stress, entropy, and an inequality constraint. A model is developed for each of the constitutive functions needed to characterize the shear response, and it is shown that the model can quantitatively reproduce the experimental response for a complex sequence of loading and unloading histories. The article concludes by providing the multidimensional counterpart for the proposed structure developed for shear.
