Finite bending and pattern evolution of the associated instability for a dielectric elastomer slab [PDF]

open access: yes, 2018
We investigate the finite bending and the associated bending instability of an incompressible dielectric slab subject to a combination of applied voltage and axial compression, using nonlinear electro-elasticity theory and its incremental version.

On designing dielectric elastomer actuators [PDF]

open access: yesJournal of Applied Physics, 2008
Subject to a voltage, a dielectric elastomer can deform substantially, making it a desirable material for actuators. Designing such an actuator, however, has been challenging due to nonlinear equations of state, as well as multiple modes of failure, parameters of design, and measures of performance. This paper explores these issues, using a spring-roll
