Analysis of Layered Composite Plates by Three-Dimensional Elasticity Theory.

Abstract

This report contains two parts: the first part is concerned with the natural vibrations of laminated anisotropic plates, and the second part is concerned with geometrically nonlinear, finite-element analysis of the bending of cross-ply laminated anisotropic composite plates. Individual laminae are assumed to be homogeneous, orthotropic and linearly elastic. A fully three-dimensional isoparametric finite element with eight nodes (i.e., linear element) and 24 degrees of freedom (three displacement components per node) is used to model the laminated plate. The finite element results of the linear analysis are found to agree very well with the exact solutions of cross-ply laminated rectangular plates under sinusoidal loading. (Author)
