Continuum theory of elasticity and piezoelectric effects in smectic A elastomers
نویسندگان
چکیده
The general continuum free energy is derived for a liquid crystalline (smectic) elastomer under small strain and orientational distortion. Using group representation theory we obtain all invariants describing the coupling of translational and orientational degrees of freedom. Possibilities of uniform rotation of the layer system under shear deformation are outlined. It is shown that in centrosymmetric materials (smectic A) the only polarizational

Unconventional elasticity in smectic-A elastomers.
We study two aspects of the elasticity of smectic- A elastomers that make these materials genuinely and qualitatively different from conventional uniaxial rubbers. Under strain applied parallel to the layer normal, monodomain smectic- A elastomers exhibit a drastic change in Young's modulus above a threshold strain value of about 3%, as has been measured in experiments by [Nishikawa and Finkelm...
متن کاملForced vibration of piezoelectric nanowires based on nonlocal elasticity theory
In this paper, a numerical solution procedure is presented for the free and forced vibration of a piezoelectric nanowire under thermo-electro-mechanical loads based on the nonlocal elasticity theory within the framework of Timoshenko beam theory. The influences of surface piezoelectricity, surface elasticity and residual surface stress are taken into consideration. Using Hamilton’s principle, t...
متن کاملSoft elasticity in biaxial smectic and smectic-C elastomers.
Ideal (monodomain) smectic-A elastomers cross-linked in the smectic-A phase are simply uniaxial rubbers, provided deformations are small. From these materials smectic-C elastomers are produced by a cooling through the smectic-A to smectic-C phase transition. At least in principle, biaxial smectic elastomers could also be produced via cooling from the smectic-A to a biaxial smectic phase. These ...
متن کاملSoft elasticity in smectic elastomers.
We investigate the soft elastic modes of smectic elastomers, that is shape change without energy cost. We use a microscopic model for their nonlinear elasticity, similar to those used for nematic elastomers. We consider two different phases of smectic elastomer; the biaxial smectic A for a simple illustration, and smectic C phases which are of great practical significance. We show that only one...
متن کاملFree Vibration Analysis of Sandwich Micro Beam with Piezoelectric Based on Modified Couple Stress Theory and Surface Effects
In this paper, the free vibration analysis of sandwich micro beam with piezoelectric layers based on the modified couple stress and surface elasticity theories are investigated. The Hamilton’s principle is employed to derive the sandwich micro beam with piezoelectric based on modified couple stress theory incorporating with Gurtin- Murdoch surface theory. The generalized differential quadrature...
