FIG. 2.

(Color online) Behavior of a dielectric elastomer actuator under several levels of equal biaxial prestresses: (a) nominal electric field vs nominal electric displacement, (b) true electric field vs nominal electric displacement, and (c) nominal electric field vs actuation stretch. The critical points for instability are marked as crosses.
