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...
متن کاملTunable 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...
متن کاملAcoustic 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....
متن کاملAn Efficient Strain Based Cylindrical Shell Finite Element
The need for compatibility between degrees of freedom of various elements is a major problem encountered in practice during the modeling of complex structures; the problem is generally solved by an additional rotational degree of freedom [1-3]. This present paper investigates possible improvements to the performances of strain based cylindrical shell finite element [4] by introducing an additio...
متن کاملScattering of Surface Acoustic Waves from an Elastic Plate Attached to a Half-Space with a Viscous Couplant
The results presented here are part of a study of the interaction between an electro-mechanical transducer plate element and wavelengths in the test structure that are comparable to the plate dimensions. The steady time-harmonic problem is reduced to a system of singular integral equations for determining the tractions generated at the interface between the plate and half-space where a thin vis...
