Abstract— The present study is devoted for the development of a mathematical model to predict the structural behavior and critical pressure of composite cylindrical shell under external pressure using finite element analysis. The composites can be tailored to match the external loading. The effect of fibre orientation angle along with stacking sequence of the composites on the loading carrying ...

The buckling analysis of stiffened cylindrical shells by rings and stringers made of functionally graded materials subjected to axial compression loading is presented. It is assumed that the material properties vary as a power form of the thickness coordinate variable. The fundamental relations, the equilibrium and stability equations are derived using the first order shear deformation theory. ...

The nonlinear vibration behaviors of stiffened cylindrical shells under electromagnetic excitations, transverse and in-plane excitations are studied for the first time in this paper. Given first-order shear deformation theory Hamilton principle, partial differential governing equations motion derived with considering von Karman geometric nonlinearity. By employing Galerkin discretization proced...
