Instructions for Day 3 of the ALERT Doctoral School 2018

Participants are kindly requested to bring a laptop with a working installation of FEniCS and matplotlib.

Instructions for the installation of FEniCS may be found at the fenics project website

Note that in Windows 10 installation is also possible in the Windows Subsystem using the method outlined for Ubuntu. Instructions may be found at the website

To test your installation save the code on the attached document as test.py and execute using python.

PhD and postdoc positions in geomechanics at UCL (Belgium) in colaboration with UGA (France) on inherent rock heterogeneity using a double scale numerical approach

The goal of this project is to investigate the multi-scale behaviour of clay rock, going from microscopic to macroscopic scale. The research will be based on multi-scale
approach and numerical method allowing to model microstructure media in a double-scale framework (FEMxFEM). The PhD position is available at iMMC (UCL) in collaboration with the 3SR Laboratory (P. Bésuelle, CNRS, UGA). A postdoc position with a similar subject is also available.

Applications should be submitted by emailing a CV together with the academic grades (detail of marks) to the supervisor Benoît Pardoen.

PhD position: Numerical modeling of localization in (partially) saturated low permeability geomaterials. Ecole Centrale Nantes/Université de Liège

This thesis deals with the constitutive modeling of low permeability partially saturated geomaterials, in the framework of enhanced poromechanics. Partial saturation means in this context that the porous network is occupied at least by two different fluid phases, having their own wetting properties. The classical poromechanical model, based on Biot’s theory, will be therefore generalized in order to account for stress/strain localization, within the solid phase, and fluid fingering, within the fluid phases. Strain localization will be treated making use of strain gradient theory and plasticity whilst partial saturation following a phase-field modeling approach to multi-phase fluid flow. To this aim, on the one hand, a fully coupled gradient constitutive law of the porous skeleton and the saturating (mixture of) fluid(s) will be assumed, which means that the free energy of the overall continuum will be a function not only of strain and mass concentrations of the fluid components, but also of their gradients. On the other hand, irreversible deformations of the solid skeleton will be modeled adopting a suitable plasticity model. This approach stems from previous results published by the
coordinator of the project [1-2] and can be partly retrieved in a line of research pursued by Collin and Kotronis, see e.g. [3-4], for what concerns the gradient approach to (un)saturated poromechanics.
