The nonlinear vibration of a surface-bonded piezoelectric-layered functionally graded (FG) cylindrical shell conveying fluid subjected to radial distributed force is theoretically analyzed. Considering the electric-fluid-structure interaction effect, a nonlinear dynamic model of pie-zoelectric layered FG cylindrical shells conveying fluid is developed. The thin-walled piezoe-lectric layered FG shell is modelled based on the improved nonlinear Donnell's shell theory with von Karman geometrical nonlinearity related to large amplitude vibration. The inviscid, incompressible, isentropic and irrotational fluid is coupled into governing equations using the linearized potential theory. The multiple time scales method is applied to solve the resulting governing equations for analyzing nonlinear behaviors of the coupled system. The obtained results are validated by comparing the natural frequencies with the prior data. The effect of flow velocity, piezoelectric voltage, external force and volume friction of FGM shells on the nonlinear dynamic behaviors of the coupled system are investigated. The results indicate that these parameters, especially the flow velocity and the applied voltages, have important influ-ences on the nonlinear dynamic characteristics of piezoelectric layered fluid-conveying FG cylindrical shells.
