Finite Element Anlaysis of Laminated Composite Plates

Abstract

A biquadratic isoparametric plate/shell bending finite element is developed to study the behavior of isotropic and laminated composite plates. The element is based an Mindlin-Reissner's theory and the principle of virtual displacements. The element is implemented in a computer program. Results are presented and compared with analytical solutions to validate this element. Good agreement is observed for thin plates, while discrepancies are noted for thick plates. Effects of various integration schemes on the element performance are presented. Convergence studies for laminated composites for different fiber orientations are also discussed.
