摘要：
In this paper, we study the electro-stress in dielectric elastomer (DE) undergoing large deformation subjected to a high voltage. The electrostriction is investigated and evaluated by the free-energy model when the dielectric permittivity does not remain constant in actuation. We investigate the nominal and true electric fields as the DE stretched with the electrostriction involved or not, and the stable domain for safe actuation is provided.
