The present work highlights on comparative investigation for the performance of active constrained layer damping treatment using PFRC and AFC patch material for controlling the nonlinear transient vibrations of laminated composite plate. In this case for making the constraining layer of the ACLD treatment for PFRC and AFC patch material is used. For modelling of ACLD in the time domain Golla-Hughes-McTavish (GHM) method is used. The Von Karman type non-linear strain displacement relations along with a simple first-order shear deformation theory are used for deriving this electromechanical coupled problem. A finite model in 3-dimensions has been developed for smart composite plate integrated with the ACLD treated patches of PFRC and AFC. The results of both the cases have been compared and it has been found that the improved performance of AFC patch over the PFRC in subsiding the transient nonlinear vibrations of symmetric cross ply laminated composite plate.
