Abstract
In this article, a micromechanically motivated constitutive model is presented for nafion membrane to capture the rate, temperature, and hydration dependency under monotonic and cyclic tensile loadings. The basic framework of this model is derived from the Arruda-Boyce viscoplastic model and is modified to include hygrothermal correction factors to show that this model can be manipulated to produce reliable results under various virtual testing conditions.
