    • Bending control and stability of functionally graded dielectric elastomers 

      Su, Yipin; Ogden, Ray W.; Destrade, Michel (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, ...

    • The effect of an exterior electric field on the instability of dielectric plates 

      Su, Yipin; Chen, Weiqiu; Dorfmann, Luis; Destrade, Michel (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 ...

    • Electro-mechanically guided growth and patterns 

      Du, Yangkun; Su, Yipin; Lü, Chaofeng; Chen, Weiqiu; Destrade, Michel (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 ...

    • Finite bending and pattern evolution of the associated instability for a dielectric elastomer slab 

      Su, Yipin; Wu, Bin; Chen, Weiqiu; Destrade, Michel (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 ...

    • Pattern evolution in bending dielectric-elastomeric bilayers 

      Su, Yipin; Wu, Bin; Chen, Weiqiu; Destrade, Michel (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 ...

    • Wrinkles in soft dielectric plates 

      Su, Yipin; Conroy Broderick, Hannah; Chen, Weiqiu; Destrade, Michel (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 ...
