The present study focuses on the effect of anisotropy on thin laminated composite plates as smart structure with distributed AFC patches using ACLD treatment, and analysis is carried out for geometrically nonlinear transient vibrations. The constraining layer made up of AFC material is attached to substrate with the help of viscoelastic layer is modeled by using Golla-Hughes-McTavish (GHM) method. Along with a simple first-order shear deformation theory the Von Kármán type non-linear strain displacement relations are used for deriving this electromechanical coupled problem. A 3-dimensional finite element model of smart composite panels integrated with the ACLD treated patches has been modeled. The objective of the paper is to reveal the damping properties of thin laminated composite plates in order to attenuate the geometric nonlinear transient vibrations.
