Dynamic Response of Cantilever FGM Cylindrical Shell
An analysis on the nonlinear dynamics of a cantilever functionally graded materials(FGM) cylindrical shell subjected to the transversal excitation is presented in thermal environment.Material properties are assumed to be temperature-dependent. Based on the Reddys first-order shell theory,the nonlinear governing equations of motion for the FGM cylindrical shell are derived using the Hamiltons principle. The Galerkins method is utilized to discretize the governing partial equations to a two-degree-offreedom nonlinear system including the quadratic and cubic nonlinear terms under combined external excitations. It is our desirable to choose a suitable mode function to satisfy the first two modes of transverse nonlinear oscillations and the boundary conditions for the cantilever FGM cylindrical shell. Numerical method is used to find that in the case of non-internal resonance the transverse amplitude are decreased by increasing the volume fraction index N.
