▎ 摘　　要

This paper is concerned with the free vibration and transient response of graphene platelets reinforced functionally graded (GPL-FG) cylindrical shell resting on elastic foundation by utilizing the Chebyshev-Lagrangian approach. The boundary constraints are realized by setting reasonable values of stiffness of the artificial virtual springs. According to FSDT, the analysis model of GPL-FG cylindrical shell is established. Then, the displacement fields are expanded in terms of the Chebyshev-Lagrangian approach. Based on the work above, Rayleigh-Ritz energy method is employed to solve the unknown coefficients of Chebyshev expansions with purpose to indicate the dynamic characteristics of the analysis model. In addition, the Rayleigh damping coefficients are taken into account to investigate the transient response results from the external excitation. A series of numerical results show the rapid convergence and precision of the present method by comparison with results obtained by the published papers and FEM. Ultimately, the analysis about the effects of parameters and factors on free vibration and transient response are discussed, including geometry and material properties, boundary conditions, stiffness of elastic foundation, loading types and Rayleigh damping coefficients.
