ON THE SCATTERING OF PLANE COMPRESSIONAL WAVES BY A SPHERICAL OBSTACLE
Abstract
The scattering of plane compressional waves by a spherical obstacle in an elastic solid, which was investigated by Ying and Truell, is examined further. For a rigid inclusion, the boundary conditions are redefined to take into considera the motion of the inclusion inside the solid. By a proper limiting process, it is shown that the solutions for a rigid insert, a fluid sphere, a cavity, or an obstacle in a fluid, are all derivable from the general results of an elastic inclusion. In each case, the rates of energy scattering due to a small obstacle are found to be inversely proportional to the fourth power of wave length.
