In this paper, free vibrations of laminated composite cylindrical shells are investigated by the global method of generalized differential quadrature (GDQ). The GDQ method was developed to improve the differential quadrature (DQ) method for the computation of weighting coefficients. The differential equations of motion are formulated using Love's first approximation classical shell theory. The...
The free vibration of a long thick laminated conical tube is studied in this paper with a beam-type model. Taken as a beam, the tube is divided into elements by cross-sections. Each cross-section is a node. In the beam-type model, the nodal forces are assumed to be uniformly distributed along the middle circle, which is the intersection of the cross-section with the middle surface of the tube....
