Computational Modelling of Multi-field Ionic Continuum Systems

The present paper presents a methodology for modelling the behavior of continua under multi-field influence, along with the architecture of its computational implementation. It is being applied for the special case of modelling multi-field ionic conductive material systems. Its computational implementation addresses generation and solution of both the constitutive and the field evolution equations. An application of this methodology for the case of electric multi-hygrothermoelasticity generates a model for materials participating in artificial muscle applications. The corresponding system of nonlinear governing partial differential equations describing the state evolution of large deflection plates made from such materials is derived as an example. Finally, initial numerical solution examples of these electro-hygro-thermally generalized Von-Karman equations are presented.
