Electro-elastic characteristics of asymmetric rectangular piezoelectric laminae

The electro-elastic characteristics of clamped rectangular piezoelectric la minated plates were analytically investigated, A fully covered electrode pi ezoelectric layer was laminated on an elastic layer to form a nonsymmetrica l laminated plate. Using the electro-elastic theory with the Kirchhoff-Love hypothesis, formulation of analyses for mechanical, electrical, and electr omechanical characteristics of the laminae are presented. Numerical analysi s was carried out using the extended Kantorovich method to yield eigenvalue s and eigenfunctions. Theoretical predictions of dynamic characteristics we re validated by comparing results with finite element analysis data. The ca lculated natural frequencies are presented in easy-to-use figures that are useful for sensor and actuator design in microelectromechanical systems (ME MS).
