Abstract
Wave propagation in uid-lled porous media is governed by Biot's equations of poroelasticity.Gassmann's relation gives an exact formula for the poroelastic parameters when the porousmedium contains only one type of solid constituent. The present paper generalizes Gassmann'srelation and derives exact formulas for two elastic parameters needed to describe wave propagationin a conglomerate of two porous phases. The parameters were rst introduced by Brownand Korringa when they derived a...Keywords
