Estimate of the Impedance of a Finite Cylindrical Shell for the Exponential Mode of Displacement

Abstract

An algorithm for computing the impedance of a finite cylindrical shell submerged into liquid is developed. The formula obtained allows estimating the maximum and asymptotic values of impedance in dependence on the frequency and wave parameter of the exponential mode of the radial displacement of the shell.
