摘要：
The present paper deals with the static buckling and post-buckling behaviour of clamped elastic laminated shallow spherical shells subjected to a uniform external pressure. Applying the Rayleigh-Ritz procedure to Marguerre's equations combined with precise pre-buckling numerical analysis, reasonably accurate solutions are obtained for buckling upper and lower pressures. The effects of fibre orientations on pre- and post-buckling behaviour, buckling loads and modes are considered. The results for composite shells are compared with those calculated for quasi-isotropic ones.
