The ALERT Workshop 2023 (33rd Edition) should be held in Aussois from 25th to 27th September, 2023. Abstracts can now be submitted for the sessions. Please submit your abstracts by email directly to the coordinators using the Workshop abstract form (doc). If you wish to publish your presentation after the Workshop on the ALERT website, do not forget to agree by ticking the corresponding box in the abstract form.
Since time for the presentations is limited, only a part of the submitted abstracts can be chosen for the oral presentations. Therefore, we invite you to submit your abstract as soon as possible. The presentation can also be submitted as a poster. The abstracts of the posters will be published in a separate booklet (ISSN registered).
The deadline for the abstract submission is May 19, 2023. For any communication about your participation to the workshops, please contact the coordinators of the workshop sessions directly.
Here is a reminder of the workshop sessions as well as a short description of each of them. The call for abstract is open for the Session 1 and Session 3 only:
- Session 1: “Energy geomechanics”
Organizers: Jean-Michel Pereira, Carlos Santamarina and Diego Manzanal.
The use of the geological subsurface is gaining interest in various energy-related applications, covering energy recovery and storage. In these applications, the physical phenomena at play in the encountered porous materials include -often in a coupled manner- heat and mass transfers, multiphase flow, reactive transport of fluids, mechanics, etc.
- Session 2: “Extraterrestrial geomechanics“
Organizers: P. Delage and F. Prada
The InSight mission, which landed on Mars in 2018, is a geophysical mission with a seismometer (SEIS) supplied by France and a penetrometer (HP3) supplied by Germany as its main instruments for measuring the thermal gradient on the surface.
Thanks to the detection of Martian earthquakes (Marsquakes), the mission was able to improve the determination of the planet’s structure (radius of the core, mantle and crust), as intended. The seismometer also detected large meteorite impacts. The Near Surface Working Group is also interested in the geological and mechanical properties of the surface. They have studied the interaction between a Martian regolith analogue and the seismometer, and estimated in advance the elastic properties, with values close to those measured on site.
The proposed session would be based on the participation of European scientists involved in the mission.
- Session 3: “Anisotropy in geomaterials: theory, experiments and modelling”
Organizers: Eleni Gerolymatou, Cino Viggiani, and Angelo Amorosi.
Anisotropy, i.e. the variation of any given property of the material with direction, can have a significant effect on the material response to loading. It is present in most types of geomaterials, ranging from granular soils to hard rocks.
Due to the significant effort required to determine in the laboratory the internal variables of the material and the additional difficulties linked to its constitutive description, it is in most applications ignored as a matter of fact. However, in the last years significant efforts have been made in both directions.
With the present topic suggestion the organizers would like to invite contributions from researchers working on anisotropy in geomaterials in the fields of constitutive law development, experimental testing and numerical simulation. The aim is to increase awareness of the significance of anisotropy, to stimulate scientific exchange and to provide a first exposure to its intricacies for younger researchers.
