In this paper we consider a scattering problem of SH-wave by a cylindrical discontinuity in an inhomogeneous elastic medium. Its inhomogeneity is assumed as ; μ=μ_0(r/a)^λ, ρ=ρ_0(r/a)^<λ-2>, and then SH-wave velocity varies as a linear function of the distance from the center of the discontinuity. An exact solution is obtained in the form of "wave sum, " and is valid for all time and space. It is shown that the cylindrical discontinuity does not cause any diffraction of SH-wave, but incident and reflected waves propagate around the discontinuity just as the diffracted wave. Therefore, in the case of our inhomogeneity no "shadow zone" exists around it. Numerical examples are also plotted in the figures to show the effect of inhomogeneous parameter λ on the stress variation around the discontinuity.
