Abstract

Arbitrary free energy functions, as is proposed by Zhao and Suo, can be applied to analyze the electromechanical stability of the dielectric elastomer. To study the electromechanical stability of mechanical force field placed on dielectric elastomer, variable free energy functions are applied to analyze the mechanical performance of dielectric elastomer. The relation among critical nominal electric field, critical real electric field, nominal stress and mechanical force field is derived, which agrees well with the experimental results. Such a result is capable of understanding better the stability conditions of dielectric elastomers and furthermore guiding the design and manufacture of sensors and actuators based on dielectric elastomers.
