摘要：

Buckling loads of circular cylindrical laminated composite panels are obtained using Sanders-Koiter (e.g. Sanders, 1959; Koiter, 1959), Love (e.g. Love, 1927) and Donnell (e.g. Loo, 1957) shell theories with a first-order, shear-deformation approach and a Rayleigh-Ritz method that accounts for different boundary conditions and material anisotropy. Results obtained using Sanders-Koiter, Love, Donnell. shell theories are compared with those obtained from finite element simulations, where the curved panels are modeled using nine-node quadrilateral continuum-based shell elements that are independent of any shell theory. Comparisons with finite element results indicate that Donnell's theory could be in error for some lamination schemes and geometrical parameters. (C) 1999 Elsevier Science Ltd. All rights reserved.
