Abstract
The present paper deals with the static buckling and postbuckling behaviour of clamped elastic imperfect laminated shallow spherical shells subjected to uniform external pressure. Three various types of initial geometrical imperfections are analysed: two local described by a convex or a concave curve and one global in the form of the Legendre polynomial. Applying the Rayleigh-Ritz procedure to Marguerre’s equations combined with the precise prebuckling numerical analysis, reasonably accurate solutions are obtained for upper and lower buckling pressures. The effects of fibre orientations on pre- and postbuckling behaviour, imperfection sensitivity, buckling loads and modes are considered. The results for composite shells are compared with those calculated for quasiisotropic ones.
