The ALERT Geomaterials Workshop 2018 will be organized from Monday, 1st October until Wednesday, 3rd October in Aussois, France. It will include the following sessions:
SESSION 1 (1st October):
“Fluid flow and strain localization: fingering and fracture processes in partially saturated materials”
- Francesca Casini (Università di Roma TorVergata)
- Giulio Sciarra (Ecole Centrale de Nantes)
- Jean Vaunat (UPC)
The workshop aims at establishing a bridge between two different scientific communities working on two different aspects of hydro-mechanical instabilities in partially saturated media. On the one hand the one studying fluid-grain displacement regimes through initially saturated granular media due to the infiltration of a wetting (imbibition) or a non-wetting (drainage) fluid. On the other hand the one whose main interest concerns the study of strain and porosity localization into (partially) saturated granular media induced by mechanical loading. The goal is to define a common framework for treating the hydraulic and the mechanical instabilities in granular media together with their mechanical and hydraulic effects.
Contributions into phase-field modeling, level-set methods, discrete elements and numerical methods, as well as Hele-Shaw experiments, X-ray micro-tomographic imaging of pore-scale displacements and imaging of the fluid front through fractures by neutron radiography and tomography are expected and welcome.
SESSION 2 (2nd October, half-day): “Geomaterials under the nanoscope”
SESSION 3 (3rd October): “Offshore Geotechnics”
The session will make a unique opportunity to overview trending topics in the field of Offshore Geotechnics. Current industry developments are indeed mobilising substantial research in the area worldwide, especially in relation to harvesting offshore renewable energy from wind, waves and tides. Marine geotechnics plays here a prominent role, as a significant portion of the targeted cost reduction requires optimised foundation/transmission systems, including shallow and deep foundations, anchors, pipelines and power cables.
Both fundamental and applied contributions are welcome to identify and discuss state-of-the-art approaches to theoretical, experimental and numerical analysis. Particularly appreciated will be research concerning soil behaviour and soil-structure interaction under cyclic/dynamic loading, as well as novel methods to predict the installation performance of offshore foundation systems.
The ALERT Workshop will be followed by the ALERT Doctoral School 2018 on Energetical methods in geomechanics.
