Using a geo-mechanical damage model to assess permeability in cracked porous media: internal length parameter issues
(Georgia Institute of Technology, 2012-01)The THHMD model is a thermo-hydro-mechanical damage model dedicated to unsaturated rocks. The present article questions one of the postulates of the model's formulation, namely using the same Representative Elementary ... -
Using Microstructure Descriptors to Model Thermo-mechanical Damage and Healing in Salt Rock
(Georgia Institute of Technology, 2014-06)Creep processes in halite (salt rock) include glide, cross-slip, diffusion and dynamic recrystallization. Diffusive Mass Transfer (DMT) can result in crack rebonding, and mechanical stiffness recovery. On the one hand, ... -

XFEM to couple nonlocal micromechanics damage with discrete mode I cohesive fracture
(2019-09)A computational tool is developed to simulate the propagation of a discrete fracture within a continuum damage process zone. Microcrack initiation and propagation prior to coalescence are represented by a nonlocal anisotropic ... -
θ-STOCK, a powerful tool of thermohydromechanical behaviour and damage modelling of unsaturated porous media
(Georgia Institute of Technology, 2008-09)A brief review of the basic points of a suction-based heat, moisture transfer and skeleton deformation equations for an unsaturated medium is presented. The main issues such as: two temperature-dependent state surfaces of ...
