Electroelastic effect

Finally, electrostriction is also involved in experiments on the electroelastic effect and attempts to determine certain electrostriction constants from such experiments have been made (Kittinger et al. (1986)). 

As pointed out repeatedly already, the alternative interpretation of these coefficients is that of a field derivative of an elastic coefficient which manifests itself in the so-called electroelastic effect. This avenue was pioneered by Hruska (1961,...

The elasticity can be related to very different contributions to the energy of the interface. It includes classical and nonclassical (exchange, correlation) electrostatic interactions in ion-electron systems, entropic effects, Lennard-Jones and van der Waals-type interactions between solvent molecules and electrode, etc. Therefore, use of the macroscopic term should not hide its relation to microscopic reality. On the other hand, microscopic behavior could be much richer than the predictions of such simplified electroelastic models. Some of these differences will be discussed below.

The above assumptions, however, have incorrect implications. For a parallel connection of material phases, the equilibrium conditions are violated at phase boundaries, while for a series connection of material phases, the compatibility conditions may not hold at phase boundaries. Nevertheless, it can be shown that these estimates may serve as upper and lower bounds enclosing the actual electroelastic moduli of the composite. For a discussion of bounds on effective elastic properties, see Christensen [54].

The effective use of dielectric elastomers (DE) in actual transducers requires the definition of rehable design tools which correctly predict their electromechanical behavior. In this chapter, we present two different approaches for modeling DE. The first approach is focussed on describing the electroelastic behavior of DEs in the framework of finite-strain electromechanics. The second approach,...
