Geometrically Nonlinear Vibrations

This paper deals with a study on the active constrained layer damping (ACLD) of geometrically nonlinear vibrations of functionally graded (FG) laminated composite plates. The constraining layer of the ACLD treatment is considered to be made of the vertically/obliquely reinforced 1-3 piezoelectric composites (PZCs). The substrate FG laminated composite plate is composed of generally orthotropic FG layers. The generally orthotropic FG layer is a fiber reinforced composite layer in which the fibers are longitudinally aligned in the plane parallel to the top and bottom surfaces of the layer and their orientation angle is assumed to vary in the thickness direction according to a simple power-law in order to make it as a graded layer only in the thickness direction. The constrained viscoelastic layer of the ACLD treatment is modeled by implementing the Golla-Hughes-McTavish (GHM) method. Based on the first order shear deformation theory, the finite element (FE) model is developed to model the open-loop and closed-loop nonlinear dynamics of the overall FG laminated composite plates integrated with a patch of such ACLD treatment. The analysis suggests the potential use of the ACLD treatment with its constraining layer made of the vertically/obliquely reinforced 1-3 PZC material for active control of geometrically nonlinear vibrations of FG laminated composite plates. The effect of piezoelectric fiber orientation in the active 1-3 PZC constraining layer on the damping characteristics of the overall FG laminated composite plates is also investigated.

In this study, an improved Fourier series method is presented for the vibration modeling and analysis of moderately thick laminated composite plates with arbitrary boundary conditions, in which the vibration displacements are sought as the linear combination of a double Fourier cosine series and auxiliary series functions. The vibration model was established using the Hamilton energy principle. To study the vibration characteristics of laminated composite plates more comprehensively, firstly, the accuracy of the current results were validated via comparison with previous results and finite element method data. A parametric study was conducted on the effects of several key parameters, such as the h/b ratio, orientation and number of layers. In this section, both solutions are applicable to various combinations of boundary constraints, including classical boundary conditions and elastic-supported boundary conditions. Secondly, in order to identify the action position of vibration and the transmission of vibration energy, the response analysis of laminated plates was studied, and the power flow field for laminated plates was analyzed. Finally, a modal test was introduced to further verify the accuracy of the method in this paper.
