摘要：
The damping of the free vibrations of laminated composite conical shells is investigated. Finite element analysis of conical shells is performed by using the first-order shear deformation theory (FOSDT). Based on proposals of other researchers a damping model is developed in connection with the energy method (EM) and applied in order to calculate the modal loss factors of laminated composite conical shells. Numerical examples for shells with linearly varying thickness are presented. Examples of calculation show a good agreement with experimental and numerical results from the literature.
