http://sepwww.stanford.edu/data/media/public/docs/sep124/jim1/paper_html/node5.html WebA formula for the speed of Rayleigh waves in isotropic materials is obtained by using the theory of cubic equations. It is expressed as a continuous function of a certain material parameter. The formula obtained by Malischewsky [Wave Motion 31 (2000) 93] is explained on the same basis and its connection with our formula is identified.
