ACOUSTIC SCATTERING FROM A SEMIINFINITE, ELASTIC, CYLINDRICAL-SHELL

A plane sound wave is obliquely incident on a semi-infinite elastic cy lindrical shell (tube) which is mounted perpendicular to a rigid plana r baffle. There is a circular hole cut in the plate, through which the tube is fitted snugly. The end of the shell, which protrudes through the baffle, is either clamped or hinged to a rigid disk; initially thi s disk is aligned flush with a baffle. The system is entirely surround ed by compressible fluids. A formal solution is obtained for the scatt ered pressure and investigated asymptotically for the case of small ka and heavy interior fluid loading.
