|Title:||Generalized differential quadrature for free vibration of rotating composite laminated conical shell with various boundary conditions||Authors:||Ng, T.Y.
|Issue Date:||Mar-2003||Citation:||Ng, T.Y., Li, H., Lam, K.Y. (2003-03). Generalized differential quadrature for free vibration of rotating composite laminated conical shell with various boundary conditions. International Journal of Mechanical Sciences 45 (3) : 567-587. ScholarBank@NUS Repository. https://doi.org/10.1016/S0020-7403(03)00042-0||Abstract:||By using the generalized differential quadrature (GDQ) method, this paper presents the orthotropic influence of composite materials on frequency characteristics for a rotating thin truncated circular symmetrical cross-ply laminated composite conical shell with different boundary conditions. The present governing equations of free vibration include the effects of initial hoop tension and the centrifugal and Coriolis accelerations due to rotation. Frequency characteristics are obtained to study in detail the orthotropic influences. Effects of boundary condition, rotating speed, circumferential wave number and geometric property are also discussed. To ensure the accuracy of the present results by the GDQ method, comparisons are made with those available in open literature and very good agreements are achieved. © 2003 Published by Elsevier Science Ltd.||Source Title:||International Journal of Mechanical Sciences||URI:||http://scholarbank.nus.edu.sg/handle/10635/51425||ISSN:||00207403||DOI:||10.1016/S0020-7403(03)00042-0|
