Diffraction of a plane sound wave on two elastic cylinders with
non-uniform coatings
L. A. Tolokonnikov Tula State University
Abstract:
In paper the analytical solution of a problem about diffraction of
a plane sound wave on two uniform elastic cylinders with radially
non-uniform coatings is received. Analytic expressions are obtained
which describe the wave fields in the containing medium and the
homogeneous elastic bodies. The boundary-value problem for the
system of ordinary differential equations of the second order is
constructed for determination of the displacement fields in
non-uniform coatings.
By means of an continuous-non-uniform elastic coatings it is
possible to change effectively scattering performances of bodies in
determinate directions if to pick up corresponding the inhomogeneity
laws for mechanical parametres of a coating. The problem is of
interest for analysis of sound diffraction on a lattice of
cylindrical bodies and also serves as a necessary element of
solution by a method of imaginary sources of a problem about sound
diffraction on the single homogeneous elastic cylinder with the
non-uniform covering which is close to acoustically soft or
absolutely rigid flat surfaces.
Keywords:
diffraction, sound waves, uniform elastic cylinder, non-uniform
coating.
