DOI: 10.1016/j.ijsolstr.2018.06.025
Abstract: Abstract This study presents the development of a thermodynamics-based constitutive model for describing the macro-mechanical behaviour of porous rocks. The model formulation is developed within the well-established framework of generalised thermodynamics, or thermodynamics with internal… read more here.

DOI: 10.1016/j.jsg.2019.103909
Abstract: Abstract Evolution of permeability in deforming porous rocks implicitly depends on both, intrinsic rock properties (porosity, pore connectivity, pore shape, and pore size) and extrinsic environmental conditions (operating stress and strain regimes). Traditionally, permeability evolution… read more here.
