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
