ALERT Workshop 2024 – Call for abstracts

The ALERT Workshop 2024 should be held in Aussois from 30th September to 2nd October, 2024. 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 24, 2024. 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 that are opened to abstract, as well as a short description of each of them:

  • Session 1: “Emerging properties in geomaterials across the scales
    Organizers: Antoine Wautier, Farhang Radjai and Francesco Froiio.

    Geomaterials exhibit a wide range of complex behaviors that are of crucial interest for engineering scale applications or for mitigating natural risk hazards. Such behaviors are often accounted for through continuum mechanics concepts such as constitutive behavior, yield surfaces, hardening law, permeability, shear or compaction bands… Given the complexity of the macroscopic behavior of geomaterials, a current strategy is to use a multi-scale approach either in the lab or in the virtual lab (with DEM, molecular dynamics, X-ray tomography, SEM…), to identify sub-components with simpler behavior. However, in the change of scale, some properties are lost and some emerge.
    In the upscaling, we face the issue of emerging properties fundamentally different from those at lower scales. For instance, sand is usually modeled as non-deformable solids interacting through elastofrictionnal contact laws, but the internal friction angle (macroscale) does not corresponds to the contact friction (micro scale) but incorporate geometrical properties of the microstructure.
    On the contrary, the huge number of degrees of freedom that exist at the microscale is compressed into a much more limited number of macroscopic degrees of freedom. For instance, the displacements and the rotations of thousands of sand grains reduce to the strain tensor (and possibly its derivatives for enriched continuum mechanics) at the representative elementary volume scale. For the stress, the well-known Love-Weber formula, compress contact based information into a second order tensor.
    Working on the mico to macro link is probably the key for a wise use of phenomenological constitutive models (e.g. physics based justification of the parameters) and for an efficient use of multiscale strategies (e.g. FEMxDEM methods save probably too much microscale information).
    In addition, fundamental knowledge on the micro/macro link may prove crucial to anticipate future use of geomaterials subjected to unprecedented loading conditions. Among other conditions, we can think of temperature rises, thawing permafrost, chemical creation or dissolution of bonds, diffusion of pollution, cyclic loadings, recycling materials, varying degrees of saturation…

  • Session 2 (half-day): “Geomechanics in the submicron-scale
    Organizers: Katerina Ioannidou and Gilles Pijaudier-Cabot.

    Geomaterials usually exhibit complex mechanical behavior across several length and time scales. The submicron scale is relevant for understanding the microstructure and mechanical response of various geomaterials such as rocks, soils, sediments etc. Such materials are usually porous or granular and have been formed under different environmental conditions. At the submicron scale, nanoscale effects become significant. This includes phenomena such as surface roughness, intermolecular forces, pore structure, and distribution of defects which can influence the mechanical behavior of geomaterials. Moreover, processes such as fluid flow through nanopores, adsorption and desorption of fluids on mineral surfaces, and chemical reactions at mineral-fluid interfaces are important for the formation and aging of the microstructure of geological materials.
    This session aims to elucidate processes at the submicron scale either with numerical or experimental techniques that are important for geomechanics. 
    We invite contributions related to, but not limited to, the following topics:
    – Multiscale modeling and simulations of geomechanical processes
    – Fluid-solid interactions and nanopore-scale transport phenomena
    – Nanoindentation and atomic force microscopy (AFM) studies of geological materials
    – Microstructure characterization and imaging techniques at submicron scales
    – Fracture mechanics and crack propagation in geomaterials
    – Applications of submicron scale geomechanics in petroleum engineering, geotechnical engineering, environmental science, and materials science
    – Experimental techniques and instrumentation for studying geomechanics at small length scales
    – Advances in nanotechnology for geomechanical applications 

  • Session 3: “Continuum-based particle methods
    Organizers: Claudio Tamagnini, Lorenzo Sanavia and Antonia Larese.

Blind Prediction Contest: Piles under monotonic and cyclic lateral loading

As part of the GEOLAB project, the Institute of Geotechnics of TU Darmstadt is calling geotechnical engineers from industry and academia to participate in an international Blind Prediction Contest (BPC) on the response of piles under monotonic and cyclic lateral loading. Two separate tests will be performed on a hollow open-ended steel pile embedded in dry sand. One test under monotonic loading and the other under quasi-static cyclic loading with more than 10,000 loading cycles.

The sand has been extensively characterised with laboratory tests, including monotonic (drained and undrained) and cyclic triaxial tests.  In addition, a standard Cone Penetration Test will be performed to characterise the sand condition in depth after compaction. All the produced data will be made available for the participants with the opening of the event on 6 May 2024.

Contestant teams can submit predictions for both tests or for the monotonic test only. All prediction methods are welcome.

General information on the tests and the BPC is made available in the event webpage.

More detailed information will be published with the opening of the event on 6 May 2024.

Stay tuned for updates by subscribing to our mailing list in the BPC website.

Call for Abstracts – Geology for a sustainable management of our planet – 3-5 Sept. 2024, Bari, Italy

Dear colleagues,

We would like to draw your attention to the forthcoming SIMP-SGI Congress (Bari, Italy, 3-5 September 2024) and to submit your abstracts to the following session:

T30. The science of clays and zeolites: from genesis to sustainable applications

Clay and zeolites minerals can contribute to achieve the ambitious goals of the European Green Deal, representing a clear response to global challenges related to broad fields of applications for industry, environment, hydrogeological risk and more. These minerals are of great interest for geosciences. Clays are the most diffuse sediments on the Earth crust, and they have a fundamental role in understanding paleoclimate, sedimentary environments, and diagenetic processes. Moreover, as zeolites, they represent a useful tool providing information on hydrothermal system and very low-grade metamorphism. Thanks to their extreme sensitivity, clays and zeolites find application in high-value technological uses by exploiting ion exchange and selective adsorption of organic molecules such as the sequestration of undesirable substances (included that of emerging concern) from aqueous, solid, and gaseous phases. Furthermore, they represent important sources of raw materials in several industrial productions as ceramic and construction materials. This session is open to studies highlighting the important contribution of these minerals in geoscience, their crystal chemistry and genesis, as well as their applications in wastewater treatment, environmental remediation and soil reclamation, landslides studies, hydrogeological risk, in the production of ceramic and more.


The deadline for abstract submission is 26 April 2024, 19:00 CET.

Hoping to see you in Bari!
