โœฆ Synopsis

An analytical solution procedure is presented for the free vibrations of shells of revolution having two bonded elastic layers and circular meridional curvature. A set of governing equations of motion are obtained by applying Hamilton's principle to the Lagrangian function of the shell vibration. These equations of motion are higher order partial differential equations having variable coefficients, and analytical solutions are obtained by expanding these variable coefficients into infinite power series. Effects of various parameters, such as material properties of the shell layers, upon natural frequencies and mode shapes are investigated.

Stiffened shells have been investigated for free vibration by using a stiffened shallow shell finite element. In the formulation the stiffener may take up any orientation within the shell element, and it need not necessarily be placed along the nodal line. A number of numerical examples of stiffened
