Abstract
Biot's theory of acoustic propagation in saturated porous elastic media has been used to systematically develop a Gurtin type variational principle which has been discretized by the finite element idealization. The resulting matrix equations of motion have been integrated in time by a general step-by-step integration scheme.Keywords
