Abstract

Viscoelasticity is known to adversely affect the performance of a dielectric elastomer actuator and limit its application. In this paper, we present a finite element method for dielectric elastomers based on a nonlinear field theory that couples viscoelasticity and electrostatics. This method is implemented in a commercial finite element software. We use the method to solve electromechanical coupling problems of viscoelastic dielectric elastomers under inhomogeneous deformation in various configurations.
