A nonlinear problem of deflection of isotropic cylindrical panels fixed along all edges and subject to transverse load was considered within the first-order shear deformation theory (FSDT) and the classical shell theory (CST). An effect of the parameter of curvature on bending and membrane components and resultants of transverse forces was analyzed. Par- ticular attention was drawn to the fact that the bending components were accompanied by transverse deformations, whereas for the membrane components, the panel was transversely perfectly rigid. Resultants of transverse forces can be significantly larger than the bending components. In failure criteria of laminated structures, only the bending transverse forces are employed.
