The flexural damping behaviors of composite laminates were characterized analytically in this study. A 2-D analytical model was developed by extending Ni-Adams model in conjunction with the laminated plate theory to include the energy dissipation contributed by the laminar stresses of σxy and σyy. The specific damping capacity (SDC) of the composite was then determined from the energy dissipation concept, which was defined as the ratio of the dissipated energy and the stored energy for per circle of vibration. The validation of the 2-D model was conducted by comparing the specific damping capacity of [0/-60/60]s and [0/90/45/-45] s laminates with the experimental data and the finite element (FEM) results. In addition, the effects of interlaminar stress on the flexural damping responses of laminated plates were also examined in the 3-D FEM analysis. Results indicated that the interlaminar stress effect may not be so significant that the current 2-D model is suitable for the evaluation of the damping responses of the laminates. Furthermore, the present predictions, as compared to the Ni-Adam and Adams-Meheri model, normally demonstrate better agreements with the experimental data and the FEM results.
