Wave scattering by infinite cylindrical shell structures submerged in a fluid medium

Abstract

This work analyzes the wave scattering by an elastic, fluid-filled, cylindrical shell structure submerged in a fluid medium and subjected to the effect of a point pressure load placed inside or outside the cylindrical shell. The shell structures modeled have constant cross-sections along their axis, corresponding to 2.5D problems. A Fourier transformation in the direction in which the geometry does not vary is applied to find the 3D field as the summation of the 2D solutions for different spatial wavenumbers.
