metadata.name: dc.description.abstract
metadata.value: In this paper the problem of finite deformations of a dielectric tube under the action of
  an electric field is considered. The tube consists of two layers, each spirally reinforced with
  fibres. The angles of the fibres in each layer are different. On the inner and outer surfaces
  of the tube and between the layers are flexible electrodes. The electric field is induced by
  applying voltage to the first or second layer, i. e. either to the electrodes on the inner side
  surface and between the layers, or to the electrodes between the layers and on the outer side
  surface. A simple model of an electroactive anisotropic incompressible material is considered
  in the analysis. The potential energy function is represented by the sum of the energy of
  the isotropic matrix in Gent form, the simplest electrical component and the energy of the
  reinforced fibres. Using a semi-inverse method, the static problem of the three-dimensional
  body is reduced to integral equations with respect to the tube deformation parameters: the
  radius of the outer layer, the multiplicity of longitudinal elongation and the twist angle.
  The influence of layer thickness on tube deformation under quasi-static increase of voltage
  is investigated. The purpose of this work is to determine the thickness of the layers at which
  the application of voltage to the different layers will cause the tube to twist in different
  directions.
