Abstract:
It is well known that dissipation accompanies vibrations in solids due to the presence of internal friction. In general, the .effect of internal friction is to produce attenuation and dispersion of elastic waves..
Wave propagation in anelastic solids provide an interesting field for the application of mathematical techniques and in addition is of practical importance
C
both to engineersand seismologists. The present work deals with the numerical computation of the variation of amplitudes for surface waves showing elastic. and anelas-tic behaviour.
