✦ Synopsis

Free, conservative vibrations of a hermetic can, simply supported at the base, are studied. The can is composed by a circular cylindrical shell and two identical circular plates connected to the shell at its ends. The arti"cial spring method, which is an extension of the classical Rayleigh}Ritz method, is used to solve the system by using substructuring. The can is studied empty and "lled with an inviscid and incompressible #uid. Fluid volume conservation is applied. The interaction between the plates and the shell via the #uid is considered, and exact expressions for the #uid velocity potential are used. The e!ect of #exibility of joints between plates and shell is investigated. Results for a #uid-"lled, simply supported shell closed by rigid ends are also obtained and compared to the classical open-end shell.

The equations of motion for straight fluid filled pipes are greatly simplified. It is found, for frequencies below a third of the ring frequency, that the radial-axial waves in cylinders are as if the circumferential motion were inextensional. This is the fundamental assumption for the analysis. The

The vibrational power flow from a line circumferential cosine harmonic force into an infinite elastic circular cylindrical shell filled with fluid is studied. To analyze the response of the shell, an integrated numerical method along the pure imaginary axis of the complex wavenumber domain is used.
