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…

Surface and volumetric elasticity characterisation of hydraulic lime mortar prisms under compression

Masonry structures predominantly work under compression; elasticity in constituent materials is therefore typically characterised during uniaxial compression tests via load and deformation measurements. In most practical applications, deformation…

Mesoscopic-Informed Residual Reinforcement Learning for Adaptive CAV Headway Control in Mixed-Autonomy Traffic

Classical constant-time-headway control limits each connected automated vehicle to predecessor-relative information, so disturbances developing farther upstream are not incorporated into the headway command until they reach the local interaction…

Learning shared hyperelastic constitutive representation from heterogeneous full-field experiments across multiple materials

A material-conditioned Physics-Augmented Neural Network is introduced for unsupervised multimaterial hyperelastic constitutive learning from experimental full-field data. The complete database comprises 30 experiments quantified by image correlation…

Geometric theory of generalised continua using moving frames

Generalised continuum theories couple the macroscopic deformation and the micro-/meso-scopic deformation of an underlying micro-structure. They can account for internal length-scale effects and higher-order mechanical loadings absent from classical…

Identification of Nonlinear Parameters in Reinforced Masonry Panels under Diagonal Compression using DIC

During seismic events, masonry walls are subjected to in-plane loadings that primarily induce compression along their diagonals. The ASTM-standardized diagonal compression test replicates these conditions on square masonry panels, allowing for the…
