Analysis of Laminated Plates by Trigonometric Theory, Radial Basis, and Unified Formulation

The unified formulation (UF) is a powerful framework for the analysis of beams, plates, and shells, because it permits us to obtain the governing equations, irrespective of the shear deformation theory being considered.

Description
Summary:The unified formulation (UF) is a powerful framework for the analysis of beams, plates, and shells, because it permits us to obtain the governing equations, irrespective of the shear deformation theory being considered. Ferreira et al propose to use this UF to derive the equations of motion and boundary conditions to analyze isotropic and laminated plates by radial basis function (RBF) collocation, according to a sinus-based shear deformation theory that accounts for through-thethickness deformations. In this Note, it is investigated how the UF can be combined with RBFs to the analysis of thick isotropic and laminated plates, using a sinus-based shear deformation theory that accounts for through-thethickness deformations.
