ACOUSTIC SCATTERING BY CYLINDRICAL-SHELLS - STUDY ON AXIAL WAVES

The study of the propagation of the axial waves are necessary to inter pret the experimental results obtained on objects constituted by a tub e limited by two hemispherical shells. In this paper, we present the c alculation of phase velocities of the waves which propagate in the len gth of a tube. These results are compared to ones obtained from a plat e which is made of the same material and which has the same thickness. An experimental study is achieved on a tube of stainless steel. It co nsists of exciting the tube on one of its ends.
