In the short course, we review classical linear poro-elasticity. We discuss the derivation of the kinematical assumptions, constitutive relations, and the resulting field equations of Biot’s formulation in detail. It will be pointed out that for an isotropic homogeneous porous material, Biot’s poro-elastic constitutive equations include three elastic bulk moduli and one shear modulus. The elastic constitutive equations are complemented by Darcy’s law resulting from a linear assumption for the (viscous) momentum exchange. It is shown how the resulting boundary value problem could be numerically solved, e.g. by means of Finite Element Methods for various application problems in geomechanics and geophysics. Further, the quasi-static poro-elastic equations are subsequently extended towards Biot’s set of equations describing acoustic waves in porous media. We derive the dispersion relations and especially highlight the (famous) 2nd compressional wave, also denotedas Biot’s wave, in the low- and the high-frequency regime. Further, we discuss how effective material properties of heterogeneous porous materials distinguish from properties of homogeneous media and present various typical examples of heterogeneities in geomechanical and geophysical applications. 

Prof. Dr. Holger Steeb, Institute for Applied Mechanics (CE), University of Stuttgart


Holger Steeb is a professor of Continuum Mechanics at the Institute of Mechanics and SC SimTech at the University of Stuttgart. Within SFB 1313 his is the principal investigator of the research projects B05 and C05. His research focuses on multi-scale and multi-phase methods for materials with inherent microstructure, such as porous media. Imaging characterization methods (e.g. high-resolution X-ray tomography or microfluidics), which dissolve the pore space in porous materials and represent small-scale physical processes, form the basis for the development of powerful scale-bridging simulation methods in his group. Holger Steeb applies the developed experimental characterization methods and numerical simulation techniques to various problems in the geosciences, such as deep geothermal energy.
