Calcaulation of Typical electromechancial Properties of Piezoelectrical Ceramic Materials
Parameters of the physical property of our piezoelectric ceramic materials can be calculated by the following equations (the unit is in SI system):

  Thin disc radial model

       

Applicable frequency range: 24~11000 kHz
For ա10, consult Product Data Sheet of the company for its physical property.

  Long thin length model

   

Applicable frequency range: 50~10000 kHz
Note;  For 1/b or 1/t 3, consult Product Data Sheet of the company for its physical property.
  Longitudinal length model    


Applicable frequency range: 10~100 kHz
For L/ա2.5, consult Product Data Sheet of the company for its physical property.

   Thin disc or plate thickness mode

Applicable frequency range: 70 kHz~MHz.
   Radial mode    

If thickness vibration is taken, the applicable frequency range is 70~500 kHz .
If extending vibration is taken, the applicable frequency range is 10~200 kHz .
Note:  A and C in the equations are coefficients related to R/r and . Please refer to Appendix A in GB1194-87.
   Thickness shear mode
