This is achieved through experimental characterization of the material as well as through the development of analytical (elastic and viscoelastic) and finite element models. In this research, quasi-static uniaxial tests are used to determine elastic and viscoelastic material constants of the VHB dielectric elastomer that is commercially available from 3M. The material constants are then used in hyperelastic and viscoelastic analytical models for comparison to experimental results of axisymmetric annular membranes subjected to electric fields. Displacement fields of non-axisymmetric membrane surfaces will be investigated using an experimental technique commonly used in the study of fluid dynamics. The knowledge gained from the above work will then be used to develop, design, and fabricate a modular actuator that can be assembled to construct a larger actuator.
