There are a number of plate-type piezoelectric devices in engineering, hence it is crucial to search for a method that can accurately acquire the electro-mechanical coupled field of a piezoelectric plate. A method for calculating the coupled field of an orthotropic piezoelectric plate with arbitrary thickness under an arbitrary electro-mechanical load is put forward in this article. First, the Green’s function solution of an orthotropic piezoelectric plate subjected to a line charge and a normal line force is derived based on the general solution of the orthotropic piezoelectric material. All stress and electric components of the orthotropic piezoelectric plate are derived when the general solution is substituted into suitable harmonic functions containing undetermined constants. Once the boundary conditions and electro-mechanical equilibrium conditions are satisfied, those constants can be solved. In addition, according to the obtained Green’s function solution and superposition principle, the coupled field of the orthotropic piezoelectric plate subjected to an arbitrary electro-mechanical load can be solved. Numerical results indicate that the convergence and precision of the method are quite good. A concise skill without repeated calculations is also presented for acquiring the coupled fields in the orthotropic piezoelectric plates with various thickness, which facilitates the effective design of plate thickness in plate-type piezoelectric devices. Finally, some valuable conclusions for the fine design of plate-type piezoelectric sensors, energy harvesters and actuators are presented based on the numerical results.

“…Therefore the cyclic strains and stress concentrations at layer bonding interfaces may reduce its reliability. Some scholars regard FGPM as the main structure and studied its stability problem, mainly for vibration problems, under external control voltage (prediction of static and dynamic responses [18], shape and vibration control [19,20] active control behavior [21] and unsteady stress oscillations [22]). Sharma et al [18] used first-order shear deformation theory to predict static and dynamic responses of the vibrating structure and studied active vibration control using lead zirconate titanate-Pt-based FGPM.…”

“…Parhizkar et al [21] analyzed the active control behavior of FGPM circular hollow cylinder and disk under electrothermo-mechanical loading. Ashida et al [22] conducted the investigation on the electro-elastodynamic problem in the functionally graded piezoelectric thin plate subjected to uniform impact pressure. The numerical results showed that the actuation voltages can cancel the unsteady stress oscillations for various values of the volume fraction exponent.…”

The active control of thermal buckling for sandwich, laminated, gradient and uniform plates with piezoelectric materials subjected to uniform temperature rise is studied. A temperature feedback control strategy with external control voltage is proposed to control the thermal buckling and the critical buckling temperature is enlarged obviously. The inter-laminar stresses for sandwich and laminated plates by the present temperature feedback control method is compared with those through the constant actuator voltage control method proposed by other researchers, and the advantage of the present method is discussed. The stress distributions of gradient plate are simulated and it is found that the variation law of stress distribution is consistent with the volume fraction distribution of the piezoelectric ceramics. The distribution of piezoelectric components on the active control of thermal buckling is also studied and it is observed from the results that the piezoelectric materials distributed near the surface of plate play more important role than near the center of plate.
