Abstract
A thermo-electromechanical formulation for the description of ionic
electroactive polymers is derived within the framework of the Theory
of Porous Media. The model consists of an electrically charged porous
solid saturated with an ionic solution. The saturated porous medium
is assumed to be incompressible. Different constituents following
different kinematic paths are considered such as solid, fluid, anions,
cations and free charges. The electromechanical and the electrodynamic
field equations are discussed. Based on the second law of thermodynamics,
a consistent model is developed. With respect to the closure problem
of the model, the needed constitutive relations and evolution equations
are presented.
