Vibration suppression of laminated plates with 1–3 piezoelectric fiber-reinforced composite layers equipped with interdigitated electrodes

Piezoelectric fiber-reinforced composites offer a great potential for applications in the vibration control of flexible structures. This paper presents an analytical formulation for structural vibration control of laminated plates consisting of 1–3 piezoelectric fiber-reinforced composite layers and orthotropic composite layers. The active control electric field is applied to the piezocomposite layers equipped with Interdigitated Electrodes (IDE). Based on the thin plate theory, the governing differential equations for axial vibration and transverse vibration are established, and the solution is obtained through the separation of variables and Fourier expansion methods. A numerical example analysis is carried out to investigate the dynamic characteristics of the laminated plates. Results show that the vibration suppression can be achieved by adopting a time-dependent control voltage. The axial vibration response along y-direction requires more time to damp out than that for x-direction due to the anisotropic properties of the laminated plates. Results presented here can be used to enhance the understanding of the static and dynamic response behavior of the 1–3 piezoelectric composite structures.
