Hybrid Data and Model Coupling for Non-Linear Multiphysics Problems: Application to Thermo-Poroelasticity

Most industrial systems involve multiple interacting physical phenomena (mechanical, thermal, chemical, electromagnetic, etc.), often strongly coupled. While there are many solvers for each physics considered independently, a completely new code is…

Hybrid Continuum–Discrete Simulation of Granular Structure Evolution in Battery Electrodes During Calendaring

Microstructural features such as porosity, tortuosity, and coordination number play a crucial role in determining energy density and efficiency. Although calendaring is a key step in electrode manufacturing, its impact on granular-scale structural…

Model-Order-Reduction for Non-Linear Fluid-Structure-Concentration Interaction Problems

In this presentation, we explore the use of proper orthogonal decomposition (POD) [1,2,3,4] and the discrete empirical interpolation method (DEIM) [5] to solve fluid-structure-concentration interaction (FSCI) [6]. Specifically, the system couples…

Predictive Wear Assessment of Plain Bearings in Variable Stator Vanes: Accounting for Geometric Tolerances in Early-Stage Design

The Variable Stator Vane (VSV) [1] system is a complex kinematic system associated with the first stages of the high-pressure compressor. It enables adjustment of the stator vane incidence angle according to the incoming primary airflow conditions…

Impact of X-ray CT calibration steps on DVC and P-DVC displacement uncertainties

X-ray tomography can be used to measure displacement fields from in situ or ex situ mechanical tests. The present work aims to quantify displacement uncertainties resulting from different reconstruction steps implemented in computed tomography. Two…

Hybrid non-intrusive local/global approaches for robust optimization leveraging surrogate models

This work extends non-intrusive local/global coupling methods to multiscale robust design optimization, building upon and further developing the framework introduced in Karaouni et al. (2025). The approach enables efficient global optimization while…

Quantification of deformation and cracking processes of an aggregate due to alkali-silica reaction using digital volume correlation from X-ray CT images

This study aims to provide insights into the location of expansion due to alkali-silica reaction (ASR) by quantifying deformations during the early stage of expansion of a single reactive andesite aggregate embedded within cement paste. One-month…
