Functionally graded material (FGM) is a modern composite material created from two components metal and ceramic. The FGM is both highly heat-resistant like the ceramic and good resilience just like metal. Today, FGMs have been used in several industries such as aviation, space, and nuclear power. The knowledge of the buckling, post-buckling, and vibration of FGM structures plays an important role in the design of these structures. In this study, the nonlinear vibration of functionally graded moderate thick toroidal shell segment surrounded by an elastic foundation are investigated. Based on the Reddy’s third-order shear deformation shell theory with the geometrical nonlinear in von Karman sense and Galerkin’s method, the governing equations are derived. The effects of temperature, material, dimension geometry parameters and foundations on characteristics of nonlinear vibration as natural frequencies, dynamic responses of shells are examined.
