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 ...
