Abstract

Two-dimensional transient shear wave propagation in viscoelastic cylindrical layered media I. Abu-Alshaikh, D. Turhan, Y. Mengi Department of Engineering Sciences, Middle East Technical University, Turkey. Abstract In this study, propagation of two-dimensional transient shear waves in viscoelastic cylindrical layered media is investigated. The multilayered medium consists of N different isotropic, homogeneous and linearly viscoelastic layers with two discrete relaxation times. A numerical technique which combines the Fourier transform with the method of characteristics is employed to obtain the solutions. The numerical results are displayed in curves denoting the variations of the stress components with time at different locations. These curves reveal clearly the scattering effects caused by the reflections and refractions of waves at the boundaries and at the interfaces. The curves also display the effects of viscous damping in the wave profiles. The curves further show tha
