Compressing a porous material will decrease the volume of the pore space, driving fluid out.
Similarly, injecting fluid into a porous material can expand the pore space, distorting the …

The coupled hydrology and mechanics of soft porous materials (such as clays, hydrogels,
membranes, and biofilms) is an important research area in several fields, including water …

Viscous fingering instability, as one of the numerous fluid instabilities and mechanisms of
pattern formation, is very common in different fields of research. First studied experimentally …

Boundary conditions between a porous solid and a fluid has been a long-standing problem
in modeling porous media. For deformable poroelastic materials such as hydrogels, the …

We perform direct numerical simulations of the flow through a model of deformable porous
medium. Our model is a two-dimensional hexagonal lattice, with defects, of soft elastic …

Bentonite has been widely used as buffer and backfill materials for nuclear waste disposal in
last few decades. The main reasons of bentonite being selected for buffer and backfill …

Two aspects of hydrogel mechanics have been studied separately in the past. The first is the
swelling and deswelling of gels in a quiescent solvent bath triggered by an environmental …

We introduce a new approach for modelling the swelling, drying and elastic behaviour of
hydrogels, which leverages the tractability of classical linear-elastic theory whilst …

The radially outward flow of fluid into a porous medium occurs in many practical problems,
from transport across vascular walls to the pressurization of boreholes. As the driving …

Poromechanics is a well-established field of continuum mechanics which seeks to model
materials with multiple phases, usually a stiff solid phase and fluid phases of liquids or …
