FREE VIBRATION ANALYSIS OF LAMINATED PLATES USING A LAYER-WISE THEORY Conference Paper

abstract

• Reddy's layer-wise theory is used to perform free-vibration analysis of laminated plates. This theory is most current and sophisticated theory in which full account is given to various three-dimensional effects. The results obtained from this theory are compared with those obtained from a full-fledged three-dimensional elasticity analysis and various equivalent single-layer theories that are available. These include: (i) the classical laminated plate theory (CLPT), (ii) the first-order shear deformation laminated plate theory (FSDPT), and the third-order shear deformation plate theory (THSDPT). The elasticity equations are solved by utilizing the state-space variables and the transfer matrix. A detailed analysis is carried out, by uncoupling the Navier Equations, to study the various mode shapes and natural frequencies of a homogeneous transversely isotropic plate. Results are also obtained for symmetric and antisymmetric cross-ply laminates.
