A Continuum Diffusion Model for Viscoelastic Materials

Abstract

A model for diffusion in polymers is established from basic principles of irreversible thermodynamics, employing the methodology of continuum mechanics. The polymeric materials are considered to respond viscoelastically, with ageing. It is shown that effects of stress on diffusion and certain anomalies in the moisture sorption process can be explained by the present model. Diffusion, Viscoelasticity, Moisture.
