In This paper, Frenkel introduced the theory of wave propagation in saturated porous media. A Second-type compressional wave, also known as the slow wave, was predicted for the first time, based on theoretical analysis. The Seismoelectric phenom[...]

The Biot-Frenkel model of fluid-infiltrated material dynamics in its original linear form is adequate to solve many problems for soils and rocks mechanics saturated with fluids. The Main interest to it was connected with applications in oil/gas [...]

Frenkel's 1944 theory of porous media acoustics is carefully scrutinized. After some manipulation, Frenkel's equations are seen to have nearly identical form to Biot's 1962 equations. The Only difference is that Frenkel includes an extraneous fl[...]

One of the most conspicuous aspects of the Biot-Frenkel theory is the existence of the slow compressional wave. An Overview is given of the various experimental techniques that were/are used to study its appearance and properties.
Un des as[...]

Four methods of upscaling coupled equations at the microscale to equations valid at the meroscale and/or macroscale for fluid-saturated and partially saturated porous media will be discussed, compared, and contrasted. The Four methods are: (1) e[...]

A Series of trixial compression experiments have been conducted to investigate the effects of induced stress on the anisotropy developed in dynamic elastic and poroelestic parameters in rocks. The Measurements were accomplished by utilizing an a[...]

In this paper we present a comparison of the linear wave analysis for four models of poroelastic materials. A Nonlinear thermodynamical construction of a two-component model of such materials requires a dependence on the porosity gradient. In th[...]
