Biot fluid theory
Weband Prevost [1980, 1982]. A general treatment of Biot’s theory in the range of nonlinear material behaviour and large deformations can be found in Coussy [1991, 2004], where the theory is reformulated using a thermody-namics approach. Fluid infiltrated porous media consist of solid skeleton and fluid material that occupies the porous space. WebOct 29, 2001 · In this paper we present an acoustic propagation model that approximates a porous medium as a fluid with a bulk modulus and effective density derived from Biot theory. Within the framework of Biot theory it is assumed here that the porous medium has low values of frame bulk and shear moduli relative to the other moduli of the medium and …
