“…The stopband behavior of such structures was further evaluated by performing a frequency response analysis. Based on the first-order shear deformation theory and von Karman nonlinear transformation theory, Shivakumar et al [14] established a finite element (FE) model with eight-node isoparametric serendipity elements to predict the active damping characteristics of the composite plates with the patches of active fiber composites. Zu et al [15] proposed a new nonlinear vibration model of a thin composite sheet in a thermal environment, in which the complex modulus approach, the power function, and the Ritz methods were adopted to introduce the nonlinear thermal and amplitude fitting coefficients into this model.…”

This study performs both theoretical and experimental studies on the vibration resistance of composite plates with damping coating subjected to impulse excitation load. A dynamic model is first proposed and the key differential equations are derived to solve the natural frequencies, time-domain vibration response, and dynamic stiffness at any vibration response point regarding the excitation point of such a coated structure. Then, a dynamic experiment system of two plate specimens with and without DC knocked by a hammer excitation is set up. The measured data indicates that the proposed dynamic model is trustworthy for predicting natural frequencies and dynamic stiffness results. Furthermore, based on the calculated dynamic stiffness data associated with the first four modes, the anti-vibration contribution of DC is quantitatively evaluated. It can be found that the coating can indeed improve the vibration resistance of the structure by up to 74.7%. In addition, the vibration suppression effect of DC is found to be closely related to the mode order of such a structure as well as the selected boundary condition.
