| Abstract | The two and three dimensional harmonic vibrations of homogeneous
viscoelastic semi-infinite media, two viscoelastic semi - infinite perfectly bonded together and homogeneous viscoelastic infinite media a re
considered in t his study. The goal of this study is to develop simple
far-field shape function for an infinite element algorithm of multilayered viscoelastic spaces . In two dimensional problem inplane and
anti-plane vibrations caused by symmetrical and anti-symmetrical modes
about the vertical axis are considered. Vibrations caused by axisymmetric
and aymmetric forces and pure torsion are considered in three dimensional
problem. In each case, general solutions for displacements, resulting
from the applied tractions, are obtained in an explicit form showing the
contribution of body waves and surface waves .
It is found t hat the continuous spectra of body waves composed of
finite number of discrete shear waves and pressure waves . The far-field
behaviour of the waves contributing to the body waves, are presented in
the general form. The first term approximation of the shear waves and
pressure waves are also investigated to facilitate the formulation of
far-field shape functions for an infinite element algorithm of multilayered viscoelastic halfspace. |
