Acoustic Scattering from a Finite Cylindrical Shell at Oblique incidence: Experimental Identification of Vibration Modes along the Shell Length

摘要

The experimental approach (M.I.I.R.: Method of Isolation and Identification of Resonances) of the acoustic scattering from a cylindrical shell enables the identification of circumferential modes of vibration (n), of resonances due to the surface wave T_0. In the case of a shell of finite length, several resonances of this wave may have the same n. These ones have various modes of vibration along the length of the shell (m). The previous method is found to enable the experimental identification of m.
