Finite element analysis of laminated composite plates.
finiteelementana00leem.pdf (3.244Mb)Abstract
A bi-quadratic isoparametric plate/shell bending finite element is developed
to study the behavior of isotropic and laminated composite plates. The element
is based on 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.
