Physical modelling of shallow foundation behaviour on collapsible unsaturated silt

Francesca Casini, Juan Jorge Muñoz, Sérgio D. N. Lourenço, Jean‐Michel Pereira et autres

Despite significant advances in laboratory testing of unsaturated soils, well-controlled boundary value data remain limited, while coupled hydro-mechanical constitutive models and numerical tools are increasingly used in practice. In this context, physical modelling provides an intermediate-scale approach to investigate field-representative behaviour and …

FFT-based solver for upscaling the thermoporomechanical behavior of infinitely contrasted porous materials

María Camila Olarte, Patrick Dangla, Jean‐Michel Pereira

We propose a Fast Fourier Transform based solver for estimating the thermoporomechanical behavior of porous materials, aiming at the periodic homogenization of microstructures with infinitely contrasted properties. Grounded on a thermoporomechanical framework, we first present the complete set of homogenized coupled properties. …

Experimental set-up in the centrifuge study of a laterally loaded energy pile

Eva Khamis, Matthieu Blanc, Thierry Dubreucq, Jean de Sauvage et autres

This paper examines the displacements of energy piles laterally loaded in dry sand using the centrifuge of the Geotechnical Centrifuge Laboratory at Gustave Eiffel University. Both grout and aluminium energy pile models are introduced, then tested by a four-point bending test to …

Fluorescence-based detection of apparent crystallization pressure in microfluidic channels

Bilal Mahmoud Hawchar, Lionel Mercury, Tulio Honorio, Matthieu Vandamme et autres

We present a fluorescence-based method for estimating apparent crystallization pressure of halite in polydimethylsiloxane (PDMS) microfluidic channels. A fluorescent dye is uniformly embedded within the PDMS matrix, converting stress-induced deformations into local fluorescence intensity changes that are calibrated against known tensile stress. …

Prix de thèse de Boussinesq – Sols quasi-saturés et dimensionnement des ouvrages au séismes : quelle marche à suivre ?

Guillaume Flood-Page, Luc Boutonnier, Jean‐Michel Pereira

Cet article s’intéresse au rôle du degré de saturation dans l’évaluation du potentiel de liquéfaction des sols. L’objectif central est de proposer une méthodologie robuste de modélisation du comportement cyclique des sols quasi-saturés. Ces derniers, assez communs à proximité de la nappe …

Mineral interphases control the thermal weakening and strengthening of granite

Wilson F. Espinoza, Timothy J. Kneafsey, Jean‐Michel Pereira, Aryong Yun et autres

While existing studies on hot rocks across various scales have provided valuable insights, they have yet to offer mechanistic explanations at the mineral level for the controversy in temperature-dependent changes in the granite mechanical properties. Most prior work, moreover, relies on samples …

Random Process Flow Matching: Generative Implicit Representations of Multivariate Random Fields

Julien Lalanne, David Picard, Lionel Boillot, Lina‐María Guayacán‐Carrillo et autres

Generative modeling provides a powerful framework for learning data distributions. These models initially relied on probabilistic methods such as Gaussian Processes (GP) for uncertainty-aware predictions and shifted towards larger trainable models to learn more complex distributions. In this work, we introduce Random …
