Large Deflection Bending Analysis of FG-GPLRC Doubly Curved Thin Shallow Shells Stiffened by Oblique Stiffeners
In the present paper, by using the Donnell shell theory and the relationship between strain and displacement of von Karman, the bending behaviors of the functionally graded graphene platelet-reinforced composite (FG-GPLRC) doubly curved shallow shells subjected to external pressure are presented and analyzed in detail. Aiming to heighten the structure's bearing capability, the FG-GPLRC stiffener system in the longitudinal, transverse and/or oblique directions is arranged at the bottom surface of FG-GPLRC doubly curve shallow shells. The improved smeared stiffener technique is used for FG-GPLRC stiffeners, and the equilibrium equation system is obtained, after that, these equations can be solved by applying Galerkin's procedure, and the expressions of large deflection bending in the explicit forms are achieved. The influences of material properties, stiffener system, and geometrical characteristics of doubly curved shallow shells on bending behavior are also considered and investigated.
