• Modeling of instability in cemented granular materials with an enhanced multiscale model · 2027

  Résumé de la publication : Micromechanics of cemented granular materials provides a critical perspective for analyzing their complex macroscopic behavior, particularly regarding the progressive degradation of microscopic inter-particle bonds.Different from phenomenological approaches, multiscale modeling offers a powerful framework for linking grainscale mechanics to macroscopic material responses. Building…

• Increasing prevalence of warm monomictic lakes in France over six decades under climate change · 2026

  Résumé de la publication : This study utilized temperature simulations from the Ottosson-Kettle-Prats Lake Model and a modified Lewis classification to analyze temporal changes in mixing-regime dynamics, temperature, density gradients, and meteorological indicators in 170 French lakes between 1959 and 1988 and 1989-2019. In the initial period,…

• Numerical implication of water–soil leakage induced by longitudinal tunnel segment dislocation opening in saturated strata · 2026

  Résumé de la publication : Water–soil leakage due to the longitudinal dislocation opening of tunnel segments in high-permeable soil strata is crucial for ensuring the longevity of underground tunnel infrastructures. This research delves into this complex phenomenon employing coupled computational fluid dynamics (CFD), discrete element method (DEM),…

• Comparative Study of Three Fine Grains Infiltration Techniques to Re–Fill Granular Materials Eroded by Suffusion · 2026

  Résumé de la publication : With the aim of remediating soils eroded by suffusion, three different techniques were explored and compared at the laboratory scale in this study to effectively infiltrate fine grains into a porous granular filter. In the first technique, which serves as a reference…

• Development of a Thermo-Mechanical Model for PVC Geomembrane—Application to Geomembrane Stability on Dam Slopes · 2026

  Résumé de la publication : Featured Application The developed temperature-dependent non-linear behavior model for a PVC geomembrane can be directly implemented in numerical modeling software, such as FLAC2D, to predict the mechanical performance and stability of geomembrane-lined slopes in dams and reservoirs. The model enables engineers to…
