| Abstract: | Based on the Timoshenko-Mindlin hypothesis and the nonlinear theory of shells,the nonlinear governing equations of motion for the laminated non-circular cylindrical thick shells are founded.And these equations are solved by using the Galerkin procedure and the method of harmonic balance.In numerical calculations,the laminated L-curve section cylindrical thick shells with both ends simply supported are investigated,and the effects of sectional shape and the radium-to-thickness ratio on the nonlinear amplitude-frequency response curves of laminated non-circular cylindrical shells are discussed.The present results are compared with available date. |
