In order to understand the characteristics of the viscoelastic coating and evaluate adhesive quality, we analyzed the effect of a thin viscoelastic layer on the propagation of surface acoustic waves in an infinite plate, which can be isotropic or anisotropic. Based on an introduction of potential functions of wave propagation in the viscoelastic layer, we started from the interaction of a thin viscoelastic...
High frequency vibrations of quartz crystal plates have been subjected to extensive studies for applications in the design and analysis of quartz crystal resonators functioning at the fundamental thickness-shear mode and its overtones. One important result needed in studies and product design is the exact dispersion relations of quartz crystal plates to be used for the validation of approximate theories,...
Finite element analysis is a powerful approach to the vibration analysis of complicated structures including the piezoelectric acoustic wave resonators such as the quartz crystal resonators, which usually vibrate at the thickness-hear mode with much higher frequency. The analysis has been done with the Mindlin plate equations for straight-crested wave solutions for displacements and vibration frequency,...
