Abstract
The Rayleigh-Ritz method has been used to analyse the buckling and pos tbuckling behaviour of thin elliptical anisotropic plates. Different l ayups and ellipse orientations were analysed and compared with finite element results showing good agreement in displacements and total ener gies in the postbuckled regime. The energy release rates along the hal f axes which govern the onset of unstable delamination growth were com puted for strains up to the third buckling mode.
