Techniques are provided for determining certain correction factors and using these correction factors in analyzing the vibration frequency characteristics of a piezoelectric material. The correction factors are developed based on the Mindlin plate theory and are introduced to correct the inaccuracies of higher-order thickness-shear cut-off frequencies. The analysis is preferably carried out during the design of a piezoelectric device incorporating the piezoelectric material and before production of the piezoelectric device. The design state may also include determining whether the device and its electrodes exhibit appropriate stiffness characteristics.

An apparatus and method for determining certain correction factors in analyzing the vibration frequency characteristics of an electroded crystal plate. The developed correction factors are introduced to correct the inaccuracies of third-order thickness-shear cut-off frequencies. The analysis is preferably carried out during the design of a piezoelectric device incorporating the electroded crystal plate before production of the device.

A method for verifying the design of piezoelectric devices includes expressing attributes of such piezoelectric device or subsystem thereof in terms of an elastic property or properties of a different subsystem or device component of the piezoelectric device. Such piezoelectric device may include a layer of piezoelectric material and one or more electrodes affixed to one or more faces of such layer. Computational complexity of models of the design are reduced by modeling displacement of the electrodes as being equal to displacement of the layer of piezoelectric material during operation of such piezoelectric device. Further reduction in computational complexity is achieved by modeling electrode displacement as being uniform within each electrode. Stress in the piezoelectric device or subsystem thereof is expressed in terms of elastic properties of a different subsystem of the piezoelectric device. Further any express dependence on strain in a subsystem or device component of the piezoelectric device may be eliminated to reduce model complexity.
