Abstract:
An approach for obtaining approximations of the Rayleigh wave velocity created by the principle
of least squares is introduced. In view of this approach, Malischewsky's approximation of the Rayleigh wave
velocity for Poisson ratios ? ?? [-1, 0.5] proposed quite recently [3] is explained. It is shown that
Malischewsky's approximation obtained by trial and error is (almost) identical with the one established by
this approach. ?? 2006 Elsevier B.V. All rights reserved.
