WebPoroelastic materials can be used to model coupled fluid-structure systems where the fluid exists within the interstitial spaces of a porous solid. The mechanical response of a porous material varies, depending on the amount of fluid present within the pores, the type of fluid, the pressure of the interstitial fluid, and the structure of the ... Maurice Anthony Biot (May 25, 1905 – September 12, 1985) was a Belgian-American applied physicist. He made contributions in thermodynamics, aeronautics, geophysics, earthquake engineering, and electromagnetism. Particularly, he was accredited as the founder of the theory of poroelasticity.

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 … Webdispersion take place in such models without any fluid presence. Biot’s Fracture Model Consider viscous fluid flow in a fracture using Biot’s approach. Combining a linearized equation for compressible viscous fluid with a continuity relation, we can obtain the equation for the viscous fluid velocity motion v, in the form: 22 (1) 2 2 0 3 c
