Reflection of Plane Wave at Traction-Free Surface of a Pre-Stressed Functionally Graded Piezoelectric Material (FGPM) Half-Space
This paper is devoted to study a problem of plane waves reflection at a traction-free surface of a pre-stressed functionally graded piezoelectric material (FGPM). The effects of initial stress and material gradient on the reflection of plane waves are studied in this paper. Secular equation has been derived analytically for the pre-stressed FGPM half-space and used to show the existence of two ...
متن کاملPropagation of Surface Waves in a Homogeneous Layer of Finite Thickness over an Initially Stressed Functionally Graded
Abstract. The propagation behaviour of Love wave in an initially stressed functionally graded magnetic-electric-elastic half-space carrying a homogeneous layer is investigated. The material parameters in the substrate are assumed to vary exponentially along the thickness direction only. The velocity equations of Love wave are derived on the electrically or magnetically open circuit and short ci...
متن کاملInterface waves in pre-stressed incompressible solids
We study incremental wave propagation for what is seemingly the simplest boundary value problem, namely that constitued by the plane interface of a semi-infinite solid. With a view to model loaded elastomers and soft tissues, we focus on incompressible solids, subjected to large homogeneous static deformations. The resulting strain-induced anisotropy complicates matters for the incremental boun...
متن کاملBleustein-Gulyaev waves in some functionally graded materials
Functionally Graded Materials are inhomogeneous elastic bodies whose properties vary continuously with space. Hence consider a halfspace (x2 > 0) occupied by a special Functionally Graded Material made of an hexagonal (6mm) piezoelectric crystal for which the elastic stiffness c44, the piezoelectric constant e15, the dielectric constant ǫ11, and the mass density, all vary proportionally to the ...
متن کاملShear horizontal surface acoustic waves in semi-infinite piezoelectrics/metal superlattices.
In this paper, an analytical method is presented for the study of shear horizontal surface acoustic waves in semi-infinite piezoelectrics/metal superlattices. The results show that the high electromechanical coupling coefficient and wide usable frequency range can be obtained in these superlattices.
