Abstract
This paper presents the damping vibration analysis of fiber reinforced plastic composite plates. For this purpose, the governing equations are formulated for a cross-ply laminated, simply-supported rectangular plate based on Classical Lamination Theory(CLT), First-order Shear Deformation Theory(FSDT), Higher-order Shear Deformation Theory(HSDT) and Discrete-Layer Theory(DLT), respectively. In the numerical examples, natural frequencies and specific damping capacities of the plates with different stacking sequences and dimensions are calculated numerically by assuming complex elastic modulus. Finally the applicability of each analytical model for damping analysis is studied by comparing with numerical results obtained respectively.
