MuPoSim 0.1 - Software for computing effective poroelasticity coefficients in multiporous media
The SW allows for computing poroelastic coefficients of porous material provides effective elastic and poroelastic coefficients of the Biot model (relevant to a quasi-static loading). Then also the so-called ?undrained test? por...

Hierarchical numerical modelling of nested poroelastic media
This paper contributes to modelling of porous materials with different levels of porosity at different length scales. We use the theory of homogenization to upscale a poroelastic description of the lowest level to higher levels of porosities...

Parallel Schwarz Domain Decomposition Solvers with Applications in Elasticity and Poroelasticity
The paper addresses the construction of parallel iterative solvers for problems of elasticity and poroelasticity. It is shown that such solvers can be built on the basis of conjugate gradient (CG) or another Krylov space iterative method wit...

Double porosity in fluid-saturated elastic media: deriving effective parameters by hierarchical homogenization of static problem
We propose a model of complex poroelastic media with periodic or locally effective properties of such a hierarchically structured poroelastic medium in representative volume elements describing the poroelastic medium at the...

Modeling flows in periodically heterogenous porous media with deformation-dependent permeability
We adapt the classical Biot model of poroelastic media for situations when the deformation has a significant influence on the permeability tensor controlling the seepage flow and on the other poroelastic coefficients. The Biot model...

Algebraic preconditioning for Biot-Barenblatt poroelastic systems
Poroelastic systems describe fluid flow through porous medium coupled with deformation of the porous matrix. In this paper, the deformation is described by linear elasticity, the fluid flow is modelled as Darcy flow. The main focus is on the...

Robust block diagonal preconditioners for poroelastic problems with strongly heterogeneous material
This paper focuses on the analysis and the solution of the saddle-point problem arising from a three-field formulation of Biot's model of poroelasticity, discretized in time by the implicit Euler method. A block diagonal-preconditioner, base...

MODELLING OF CORTICAL BONE TISSUE AS A FLUID SATURATED DOUBLE-POROUS MATERIAL - PARAMETRIC STUDY
In this paper, the cortical bone tissue is considered as a poroelastic material with periodic structure represented at microscopic and mesoscopic levels. The pores properties of the poroelastic matrix fractured by fluid-filled pores...

Anisotropic behaviour of an osteon multi-scale model
An osteon, the construction unit of cortical bone tissue, can be modelled with help of the two-scale description as poroelastic body with characteristic periodic. The effective poroelasticity coefficients obtained by this procedure ...
