A Piezoelectric Anisotropic Plate Model
We mathematically justify a reduced piezoelectric plate model. This is achieved considering the three-dimensional static equations of piezoelectricity, for a nonhomogeneous anisotropic thin plate, and using the asymptotic analysis to compute the limit of the displacement vector and electric potential, as the thickness of the plate approaches zero. We prove that the three-dimensional displacemen...
متن کاملChanges in Frequencies of a Laminated Plate Caused by Embedded Piezoelectric Layers
T HE three-dimensional linear theory of elasticity is used to delineate the effect of the thickness, stiffness, and mass density of piezoelectric (PZT) layers on the ® rst ® ve natural frequencies of a simply supported graphite/epoxy laminated plate with PZT layers embedded in it. Platelike smart structures are usually made of PZT patches either embedded in or bonded to the bounding surfaces of...
متن کاملInelastic light scattering by 2D electron system with SO interaction
Inelastic light scattering by electrons of a two-dimensional system taking into account the Rashba spin-orbit interaction (SOI) in the conduction band is theoretically investigated. The case of resonance scattering (frequencies of incident and scattered light are close to the effective distance between conduction and spin-split-off bands of the AIIIBV-type semiconductor) is considered. As oppos...
متن کاملTREFFTZ PLANE ELEMENT OF PIEZOELECTRIC PLATE WITH p-EXTENSION CAPABILITIES
This paper is concerned with the development of Trefftz p-element for twodimentional piezoelectric materials. Solutions in Stroh formalism for transversely isotropic piezoelectric materials are used for the intra-element displacement and electric potential (DEP) fields together with an independent DEP frame function field along element boundaries. The formulation is based on a modified variatio...
متن کاملElectro-Mechanical Buckling of a Piezoelectric Annular Plate Reinforced with BNNTs Under Thermal Environment
In this article, axisymmetric buckling behavior of piezoelectric fiber reinforced polymeric composite (PFRPC) annular plate subjected to electro-thermo-mechanical field is presented utilizing principle of minimum potential energy. Boron-nitride nanotubes (BNNTs) are used as fibers. Full coupling between electrical, mechanical and thermal fields are considered according to a representative volum...
