A boundary value problem of orthotropic piezoelectric solid circular cylinder which is in the state antiplane shear deformation studied. The whole surface loaded by an equilibrium axial traction. This paper gives analytical solution considered deformation.

The dispersion analysis in a fluid filled and immersed thermo–electro elastic hollow cylinder composed of homogeneous, transversely isotropic material is studied within the frame work of linear theory of elasticity. The motions of the cylinder are formulated using the constitutive equations of a transversely isotropic piezo–thermo elastic material with a preferred material direction collinear w...

In this paper ,the general solution of steady-state one dimensional asymmetric thermal stresses and electrical and mechanical displacements of a hollow cylinder made of functionally graded material and piezoelectric layers is developed .The material properties ,except the Poisson's ration, are assumed to depend on the variable radius and they are expressed as power functions of radius. The temp...

We derive a one-dimensional model from the three-dimensional equations to analyze electromechanical deformations of a piezoceramic cylinder. We show that its extensional and torsional deformations are coupled if the axis of polarization at a point makes a nonzero angle with the axis of the cylinder and the projection of the polarization vector on a cross section is perpendicular to the radial l...

Abstract The object of this paper is the Saint-Venant torsion a solid elliptical cylinder made orthotropic homogeneous piezoelectric material. We find shape cross section which does not warp under applied torque. sizes section, has maximum value torsional rigidity for given cross-sectional area, are also determined.

When a rock sample is pressed by a force, the pressure on the crystal lattice generates an electrical field around the quart grains due to the piezoelectric effect. If a rock is saturated by conductive fluid, the relative motion between the pore fluid and the matrix solid generates an electromagnetic field due to seismoelectric conversion, and the permeating of fluid into new microcracks made b...
