Description
Constant mechanical load offers stabilization in the electromechanical deformation of dielectric elastomer. Because of the viscoelasticity, the electromechanical coupling of dielectric elastomer evolves under a pair of dead loads. The evolutionary paths of electromechanical stability are classified and investigated, where a transformation, from unstable to stable, is identified. Under the proposed theoretical model, the critical time and critical load on the transformation is determined, providing a path forward for improving performance of dielectric elastomer based actuators.
