A composite piezoelectric transducer is made of a piezoceramic (NEPEC 6), aluminum, and an adhesive layer.
Electrical terminals are attached to electroded surfaces of the piezoceramic where a potential V is applied. Determine the terminal input admittance Y over a frequency range spanning the first natural frequency. Figure 176.1 Piezoelectric Transducer Problem Sketch Material Properties
