Modeling of Porous Rock: Digitization and Finite Elements Versus Approximate Schemes Accounting for Pore Shapes

We consider connections between microstructure and elastic properties of porous/microcracked materials on the example of Fontainebleau sandstone. The microstructural information (average shapes of pores) required for adequate modeling of the isotropic elastic properties is identified. It is shown th...

Description
Summary:We consider connections between microstructure and elastic properties of porous/microcracked materials on the example of Fontainebleau sandstone. The microstructural information (average shapes of pores) required for adequate modeling of the isotropic elastic properties is identified. It is shown that, if this information is utilized, the usual effective media schemes provide satisfactory predictions of the effective elastic properties.
