TL;DR: In this paper, the response of a penny shaped crack embedded in an infinite, isotropic elastic medium to an incident plane harmonic shear wave is considered and the singular behavior of the stress components at the edge of the crack is discussed.

TL;DR: In this paper, the problem of diffraction of axisymmetric harmonic elastic waves by a rigid circular disc is reduced to finding the solution of a pair of integral equations of the second kind suitable for iteration at low frequencies.
Abstract: The problem of the diffraction of axisymmetric harmonic elastic waves by a rigid circular disc is reduced to finding the solution of a pair of integral equations of the second kind suitable for iteration at low frequencies. Using the principle of contraction mapping, the rate of convergence of the iteration procedure is discussed and the error caused by stopping at any particular stage estimated. Detailed calculations are given for plane compressional waves at normal incidence.
