Free vibration analysis for composite laminated doubly-curved shells of revolution by a semi analytical method

In this paper, a unified Jacobi-Ritz method is present to analyze the free vibration of composite laminated doubly-curved shells of revolution with general boundary conditions. The composite laminated doubly-curved shells of revolution are divided into their segments in the axial direction, and the theoretical model for vibration analysis is formulated by applying first-order shear deformation theory. The Jacobi polynomials along the axial...
