Abstract
The force-displacement relations of a cylindrical!} curved anisotropic sandwich panel faced with fiberreinforced plastic (FRP) are derived by the complementary energy principle. The Rayleigh-Ritz method is then used for the buckling analysis of simply supported panels. The results show that 1) the quantitative difference between positive and negative shear buckling loadings; 2) panels of small aspect ratio are efficient to carry negative shear loads and those of large aspect ratio to carry marginally higher positive shear loads; 3) a fiber orientation angle of 50 deg measured from the curved edge provides maximum shear buckling strength; and 4) deeply curved shells resist higher negative shear loads and shallow shells higher positive shear loads.
