Thermal analysis for cracks near interfaces between piezoelectric materials

چکیده

A crack of arbitrary size and orientation near bimaterial interfaces between dissimilar thermopiezoelectric materials is considered . A system of singular integral equations for the unknown thermal analog of dislocation density defined on the crack faces is derived by way of the Stroh's formulation and the thermoelectroelastic Green's fUflctions developed recently. The stress and electric displacement intensity factors are then computed by numerically solving these singular integral equations. Numerical resuHs are obtained to elucidate the effects of crack orientation.

Cracked piezoelectric layer bounded between two orthotropic half-planes

This paper deals with the behavior of anti-plane shear crack in a piezoelectric layer bounded between two orthotropic half-planes within the framework of linear electroelasticity. The crack surfaces are assumed to be permeable or impermeable. The analysis is based on the stress fields caused by Volterra-type screw dislocation in the medium. Fourier transforms are used to reduce the dislocation ...

Multiple moving cracks in an orthotropic strip sandwiched between two piezoelectric layers

In this paper, the solution of a moving Volterra-type screw dislocation in an orthotropic layer, bonded between two piezoelectric layers is obtained using complex Fourier transform. The dislocation solution is then employed as strain nuclei to derive singular integral equations for a medium weakened by multiple moving cracks. These equations, which are classified as, Cauchy singular equations, ...

In-Plane Analysis of an FGP Plane Weakened by Multiple Moving Cracks

In this paper, the analytical solution of an electric and Volterra edge dislocation in a functionally graded piezoelectric (FGP) medium is obtained by means of complex Fourier transform. The system is subjected to in-plane mechanical and electrical loading. The material properties of the medium vary exponentially with coordinating parallel to the crack. In this study, the rate of the gradual ch...
