RADIATION PROPERTIES OF CELLULAR SHELLS.

Abstract

The differential equations of motion governing the elastic response of the cellular shell submerged in an infinite acoustic medium are derived from the Lagrangian of the system by use of Hamilton's Principle. Solutions for the far-field scattered pressure are obtained by use of the asymptotic expansion of Hankel Functions. Numerical results are presented for the non-dimensional far-field pressure in water for frequency parameters of 0.05 to 10.0 over a wide range of various geometric ratios which determine the structure of the shell.
