Comment on "on electromechanical stability of dielectric elastomers" [Appl. Phys. Lett. 93, 101902 (2008)]

Abstract

We would like to thank Díaz-Calleja [Appl. Phys. Lett. 93, 101902 (2008)] for their insight and help on "On electromechanical stability of dielectric elastomers;" unstable domain of electromechanical coupling system of neo-Hookean-type silicone was analyzed by Díaz-Calleja Different from that given in the paper of Díaz-Calleja, in the current work, the elastic strain energy function with two material constants was used to analyze the stable domain of electromechanical coupling system of Mooney-Rivlin-type silicone, and the results seem to support the theory of Díaz-Calleja. © 2009 American Institute of Physics.
