| Abstract: | Based on the first order shear deformation theory,the nonlinear dynamic equations including transverse shear deformation and initial geometric imperfections were obtained by Hamilton's principle and solved by the semi-analytical method.The nonlinear partial differential equations are transformed to ordinary differential equations by the expansion of displacement and load in Fourier series along circumference,which are numerically solved by finite difference method.The dynamic response of laminated composite cylindrical shell was discussed. |

| Keywords: | composite materials cylindrical shell non-linear dynamic response semi-analytical method |
