Identification of characteristic parameters for electro-active polymer membranes including viscous effects at finite strain

Description

This contribution is concerned with the modeling and subsequent simulation of the behavior of electroactive polymer membranes. Mathematical models based on the assumptions of
continuum physics contain not only hyperelastic characteristics and viscosity of the material, but also dielectric and electrostrictive effects in a coupled manner. Material constants remain
to be identified for the final description of any particular dielectric elastomer. Tensile tests at large strain, relaxation tests and measurements of deformation under electric actuation are
required to provide the necessary data sets.
We present a corresponding model and its realization within a multi-purpose open-source python finite element package. We explore the capabilities of this approach for VHB4910, for
which we extract the necessary characteristic parameters from various sets of measurement data provided by Wissler and Mazza
