Abstract

In this work, constitutive equations and proper finite element formulation for modeling electromechanical coupling including finite viscoelasticity have been developed. For this objective, tools from continuum mechanics have been adopted for developing a phenomenological model that accounts for large deformations combined with the electromechanical coupling and the viscous nature of EAPs. Moreover, polymers are nearly incompressible materials, thus, a mixed finite element formulation was developed and implemented in a finite element package (e.g. Abaqus) for realistic simulations of EAPs. Moreover, a material parameter identification procedure has been developed in order to specify a proper strain energy function for the acrylic elastomer "VHB".
