Fast 3D Diffusion for Scalable Granular Media Synthesis

Simulating granular media, using Discrete Element Method is a computationally intensive task. This is especially true during initialization phase, which dominates total simulation time because of large displacements involved and associated kinetic…

Breaking the Black Box: Inherently Interpretable Physics-Informed Machine Learning for Imbalanced Seismic Data

Earthquakes are the most damaging natural disasters in the past century, making ground motion models (GMMs) critical components in seismic risk mitigation and infrastructure design. With rapidly expanding strong motion databases, machine learning …

Tsunami modeling with dynamic seafloors: a high-order solver validated with shallow water benchmarks

Recent scientific studies have suggested that, in certain physical configurations, the time-dependent behavior of earthquake rupture and seafloor (bathymetry) motion can leave observable near-field signatures in tsunami wave generation and…

A strategy with reduced models dedicated to parametrized nonlinear strongly coupled thermo-poroelasticity problems

This paper offers an approach to deal with parametrized nonlinear strongly coupled thermo-poroelasticity problems. The approach uses the LATIN-PGD method and extends previous work in multiphysics problems. Proper Generalized Decomposition (PGD)…

Modélisation simplifiée de l’usure dans les liaisons à contact conforme – Application aux aubes à calages variables

Mastering engine maintenance is a key issue for airline companies. To avoid aircraft being grounded for extended and costly periods, it is strategically important to anticipate maintenance cycles, and therefore the wear of systems. In this context,…

Non-local approach to fretting fatigue problems, modelling contact behaviour under complex conditions

Fretting phenomenon occurs when two contacting solids are subjected to vibratory loads, resulting in micro-slip at the contact interface. This phenomenon can lead to micro-cracks initiation and wear debris formation within the contact region. Under…

Une approche multiéchelle avec modèles réduits pour le calcul de problèmes paramétrés fortement couplés en thermo-poroélasticité

Solving strongly coupled thermo-poroelasticity problems remains a major challenge due to the complexity of their numerical treatment. Indeed, the presence of coupling terms can degrade the conditioning of the systems to be solved, as well as…
