Paper Abstract

A non-linear viscoelastic model for finite deformations of dielectric elastomer membranes using Christensen's theory of viscoelasticity is developed. For a time efficient numerical solution, the constitutive integral equations with a time dependent kernel (relaxation modulus) are reformulated into a recurrence form using Feng's recurrence formula and solution for the principal stretches are obtained. Uniaxial constant load tensile tests are conducted and compared with theoretical predictions. The model is also valid for small linear deformations.
