Finite bending and pattern evolution of the associated instability for a dielectric elastomer slab
(Elsevier, 2018-09-21)
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 ...
Wrinkles in soft dielectric plates
(Elsevier, 2018-07-04)
We show that a smooth giant voltage actuation of soft dielectric plates is not easily obtained in practice. In principle one can exploit, through pre-deformation, the snap-through behavior of their loading curve to deliver ...
The effect of an exterior electric field on the instability of dielectric plates
(The Royal Society, 2020-07-29)
We investigate the theoretical nonlinear response, Hessian stability, and possible wrinkling behaviour of a voltage-activated dielectric plate immersed in a tank filled with silicone oil. Fixed rigid electrodes are placed ...
Pattern evolution in bending dielectric-elastomeric bilayers
(Elsevier, 2019-07-24)
We propose theoretical and numerical analyses of smart bending deformation of a dielectric-elastic bilayer in response to a voltage, based on the nonlinear theory of electro-elasticity and the associated linearized incremental ...
Electro-mechanically guided growth and patterns
(Elsevier, 2020-07-01)
Several experiments have demonstrated the existence of an electro-mechanical effect in many biological tissues and hydrogels, and its actual influence on growth, migration, and pattern formation. Here, to model these ...
Bending control and stability of functionally graded dielectric elastomers
(Elsevier, 2021-01-18)
A rectangular plate of dielectric elastomer exhibiting gradients of material properties through its thickness will deform inhomogeneously when a potential difference is applied to compliant electrodes on its major surfaces, ...
