✦ Synopsis

This paper is a study of the dynamic response of a cylindrical shell imperfectly bonded to a surrounding elastic continuum of infinite extent. The shell and the continuum are joined together by a bond which is thin and elastic. As the applied load an axisymmetric ring pressure moving in the axial direction along the interior of the shell is treated. The steady state solution of the problem is obtained by using the Fourier transform method with respect to an axial space variable, it being assumed that the shell bends according to a thick shell theory, while the surrounding continuum behavior is in accord with the linear theory of elasticity. The critical speed of the applied load for which a resonance effect occurs in the system is obtained and is plotted as a function of the stiffness of the bond. For subcritical load speeds the radial displacements of the shell are calculated and are shown graphically for several values of the bond stiffness. The results are also compared with those from the classical thin shell theory.
