Intergranular pressure solution (IPS) is an important compaction and deformation mechanism in quartzose rocks, but the kinetics and rate-controlling process remain unclear. The aim of the present study is to test microphysical ...

Compaction localization was observed in Diemelstadt sandstone during triaxial experiments over a broad range of effective pressures (60-165 MPa). High resolution X-ray CT imaging was used to resolve the 3D the geometry of ...

Using a classical averaging approach, we derive a two-phase theory to describe the deformation of a porous material made of a matrix containing voids. The presence and evolution of surface energy at the interface between ...
