Analysis of Electromechanical Behavior of Dielectric Elastomer by Finite Element Method

抄録

Dielectric elastomers are functional materials that can convert electrical energy to mechanical energy. When the voltage is applied thought the dielectric elastomers, the remarkable strains will appear. In addition, when the fibers are embedded in dielectric elastomer actuators, the performance of the actuators will be promoted observably and anisotropically. A constitutive model is proposed in this work for finite element modeling and simulation of dielectric elastomer actuators of cylindrical shape. The Mooney-Rivlin strain energy potential is used for describing the large strain mechanical response of the dielectric elastomer. Electromechanical tests under different dead load levels were simulated by MSC. Marc. The results verify applicability of the Mooney-Rivlin model.
