Buckling analysis of functionally

The linear buckling behavior of functionally graded toroidal shell segments with corrugated core under axial compression using the first-order shear deformation theory is presented in this paper. The homogeneous technique is applied for shear deformable corrugated core. Approximate analytical solutions are assumed to satisfy the simply supported boundary conditions and the adjacent equilibrium criterion is applied to obtain closed-form relations of buckling loads.

The nonlinear buckling behaviors of the functionally graded graphene platelet reinforced composite (FG-GPLRC) doubly curved shallow shells under external pressure in the thermal environment are introduced and investigated in this paper. The Donnell shell theory and the strain-displacement relationship of von Karman are used. At the bottom surface of FG-GPLRC doubly curve shallow shells, the FG-GPLRC stiffener system in the transverse, longitudinal, or/and oblique directions is installed to increase the bearing capacity of the shallow shells.

An analytical approach of nonlinear buckling and postbuckling analysis of core-corrugated functionally graded carbon nanotubes reinforced composite (FG- CNTRC) cylindrical panels under axial compression is presented in the present study. A homogenization technique is applied for the corrugated core with thermal effects. The nonlinear stability equation system of panels is formulated by using the Donnell thin shell theory with the von Kármán geometrical nonlinearities.
