Large Amplitude Vibration of Anti-symmetrically Laminated Imperfect Cylindrical Thick Shell

In this paper the Donnell-type shell theory is extended to include the transverse shear forthe analysis of a anti-symmetric angle-ply imperfect cylindrical shell with mixed boundary conditions. Amulti-mode solution is presented in the form of generalized double Fourier series with time-dependentcoefficients determined by the method of harmonic balance for undamped free vibrations.Numerical re-sults for fundamental nonlinear free vibration of cylindrical laminates are presented graphically for dif-ferent parameters and compared with available data.Manuscript received on June 8, 1994 This work is supported by the National Educational Commite of China for visiting scholar and by the Natural Science Research Council of China
