Vibration analysis of the coupled doubly-curved revolution shell structures by using Jacobi-Ritz method

In this paper, a unified Jacobi-Ritz formulation is presented to investigate the free vibrations of various coupled doubly-curved revolution shell structures with arbitrary boundary conditions. The combined shell structure consists of the paraboloidal, elliptical, hyperbolical, cylindrical and spherical shells. Multi-segment partitioning strategy and Flügge's thin shell theory are adopted to establish the theoretical model. Regardless of the...
