✦ Synopsis

A plane sound wave is obliquely incident on a semi-infinite elastic cylindrical shell (tube) which is mounted perpendicular to a rigid planar 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 this disk is aligned flush with a baffle. The system is entirely surrounded by compressible fluids. A formal solution is obtained for the scattered pressure and investigated asymptotically for the case of small ka and heavy interior fluid loading.

A plane sound wave is incident upon a system of two concentric cylindrical shells. Linking the shells in such a way that reaction forces and bending moments are transmitted to the shells is a disk or annulus which can undergo rigid body motion only, and which remains perpendicular to the shells at t

In this paper, the problem of the vibrational response of a thin-walled cylindrical, semi-in"nite shell subject to edge loads is addressed. The loads consist of an axial force, a circumferential force, a radial force and a bending moment. Approximate solutions for input mobilities as well as cross-m
