| Abstract: | This paper investigates the global stability analysis for laminated composite coner-cylindrical connected shells using finite element method in consideration of nonlinear elasticity behaviour of composite materials. The modified Hahn-Tsai nonlinear constitutive relationship is applied. The initial stress state of the shell in the prebuckling state is obtained by complete shell theory. The effect of transverse and shear nonlinearity on the global stability for the shells under axial compression and lateral external pressure is also studied. |
