Vibration control of laminated composite plates using embedded smart layers

Analytical solutions and finite element results of laminated composite plates with smartmaterial layers embedded in them are presented in this study. The third-order plate theory of Reddy isused to study vibration suppression characteristics. The analytical solution for simply supported boundaryconditions is based on the Navier solution procedure. The velocity feedback control is used. Parametriceffects of the position of the smart material layers, material properties, and control parameters on thesuppression time are investigated. It has been found that (a) the minimum vibration suppression time isachieved by placing the smart material layers farthest from the neutral axis, (b) using thinner smartmaterial layers have better vibration attenuation characteristics, and, (c) the vibration suppression time islarger for a lower value of the feedback control coefficient.
