WebMay 9, 2012 · Biot’s theory of wave propagation in porous media includes a characteristic frequency which is used to distinguish the low-frequency from the high-frequency range. Its determination is based on an … 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.
