Abstract
A preliminary study is made of the effectiveness of cubic spline functions when used in potential-energy-based analyses of symmetrically-laminated, composite rectangular plates having orthotropic or anisotropic material properties. The problem under consideration is the determination of laminate natural frequencies and a first-order shear deformation plate theory is used. The analysis procedures employed are the Rayleigh-Ritz and finite strip methods. The numerical results presented show that the use of cubic spline functions is efficient for moderately-thick laminates and is particularly promising for anisotropic material However, for truly thin laminates the efficiency is reduced considerably.
