Abstrakt: This paper presents the analytical approach to investigate the nonlinear forced vibration and dynamic buckling of the variable thickness functionally graded cylindrical shells subjected to mechanical load. The nonlinear motion equations of FGM cylindrical shell with variable thickness based on classical shell theory and von Kármán geometric nonlinearity are derived. The Galerkin method and the fourth-order Runge–Kutta method are applied to solve the governing equations of dynamic system. The effects of material (coefficient k) and geometric parameters on the nonlinear forced vibration and dynamic buckling behavior of the FG shell with variable thickness are examined in detail.
