Acoustic Scattering by Shell-Covered Seafloors

Benthic shells are in the broad acoustic category of complex finite-sized shapes for which there is no exact mathematical solution to describe the acoustic scattering. Subsequently, the research program is a combination of theoretical analysis, numerical simulations, laboratory experimentation at WHOI, and comparison between models developed in this program and scattering data collected at sea....

Acoustic scattering from an infinitely long cylindrical shell with an internal mass attached by multiple axisymmetrically distributed stiffeners

A thin infinitely long elastic shell is stiffened by J in number identical lengthwise ribs distributed uniformly around the circumference and joined to a rod in the center. The 2D model of the substructure is a rigid central mass supported by J axisymmetrically placed linear springs. The response of the shell–spring–mass system is quite different from a fluid couple the displacement of the shel...

Multistability in acoustic resonance scattering

2014 Resonant scattering of sound by finite physical structures is considered as a possible means of producing bistability in diffusion of sound waves. Nonlinear dependence of the sound propagation velocity upon the sound intensity is needed in order to provide proper conditions for the insurgence of bistability. Multistability behaviour is considered as a possibility in the concurrence of prop...

Tunable cylindrical shell as an element in acoustic metamaterial.

Elastic cylindrical shells are fitted with an internal mechanism which is optimized so that, in the quasi-static regime, the combined system exhibits prescribed effective acoustic properties. The mechanism consists of a central mass supported by an axisymmetric distribution of elastic stiffeners. By appropriate selection of the mass and stiffness of the internal mechanism, the shell's effective...
