摘要
A higher-order, geometrically nonlinear theory of transversely isotropic symmetrically laminated composite plates is formulated and their post-buckling behavior is analysed. The numerical illustrations emphasize the role played by transverse shear deformation, transverse normal stress, higher-order effects and the character of in-plane boundary conditions. The results obtained within the present higher-order theory are compared with those of first-order transverse shear deformation and classical (Kirchhoff) theory, and conclusions on their range of applicability and the influence of various parameters are outlined. © 1990.
