Abstract
Composite laminated plates are a typical and relevant application of composite materials in various industries. Such structures are heterogeneous in the thickness direction and orthotropic in each lamina plane. Most of the methods for plate analysis are based on the finite element method. ill this paper it is proposed to interpolate the system of partial differential equations by radial basis functions, in particular by thin-plate splines. The thin-plate splines (TPS) method represents an alternative to multiquadrics (MQ) radial basis functions. The TPS method does not rely on a shape-parameter like the MQ method, being this a more stable approach. Composite structures can be analysed by various sets of shear deformation theories: the classical Love-Kirchhoff plate theory, the first-order shear-deformation theory, the third-order shear deformation theory and layerwise theories. ill this paper we apply the TPS method together with the third-order shear deformation theory for the analysis of moderately thick laminated plates. The methodology proves to be stable and accurate.
