Vibration of Piezoelectric Crystal Plates by Jiashi Yang

By Jiashi Yang

The first modern textual content specializing at the dynamic difficulties of piezoelectric crystal plates for resonant acoustic wave units (such as resonators, filters, and sensors) considering that H F Tiersten's booklet in 1969. This publication presents an updated, systematic and complete presentation of theoretical effects on waves and vibrations in quartz crystal plates. It expounds at the software of the theories of elasticity and piezoelectricity in acoustic wave units made of crystal plates via a assurance spanning from classical effects on acoustic wave resonators, as much as present-day functions in acoustic wave sensors.

This textual content starts with the exposition of the best thickness modes and numerous frequency results in them as a result of electrodes, mass loading, touch with fluids, air gaps, etc., and maintains directly to the extra complex shear-horizontal modes, in addition to straight-crested modes various alongside the digonal axis of circled Y-cut quartz. Modes various in either one of the in-plane instructions of crystal plates also are addressed.

The research inside of are according to the 3-dimensional theories of piezoelectricity and anisotropic elasticity with quite a few approximations whilst wanted. either loose vibration modes (stationary waves) and propagating waves are studied during this textual content. pressured vibration is usually taken care of in a couple of places.

This e-book is meant to function an informative connection with body of workers who hire piezoelectric crystal plates during their profession.

Contents:

  • Theory of Piezoelectricity
  • Thickness Modes in Plates: Elastic Analysis
  • Thickness Modes in Plates: Piezoelectric Analysis
  • Shear-horizontal Waves in Unbounded Plates
  • Shear-horizontal Vibrations of Finite Plates
  • Waves Propagating alongside Digonal Axis
  • Vibration of oblong Plates
  • Scalar Equation for Thickness Modes

Readership: specialist engineers operating with Piezoelectric Crystal Plates.
