Conception d'un test de fretting in-situ pour la tomographie à rayons X

Les assemblages mécaniques sont souvent soumis à des vibrations qui génèrent un micro-frottement au niveau des contacts : du fretting. Ces légers déplacements peuvent générer des fissures de et/ou une usure qui réduisent la durée de vie de l…

Bond behavior of GFRP bars in concrete with carbon nanotubes

This work investigates the adherence of 12.7 mm glass fiber-reinforced polymer (GFRP) bars in concrete with carbon nanotubes (CNT) through pull-out tests. Eighteen specimens were used to investigate the impact of CNT content (0% and 0.05% by weight…

Approches numériques avancées pour le recalage de modèles en dynamique vibratoire et en contexte industriel

In structural dynamics, the modified constitutive relation error is a widely used functional for model updating. The method involves a two-step iterative process to minimize the functional: first, regions with high modeling errors are localized,…

Asynchronous domain decomposition method in structure mechanics -- case of the global/local coupling

The analysis and design of complex structures can be time-consuming and computationally intensive, especially for large-scale problems. Domain decomposition methods have become a powerful tool in structural mechanics to address these challenges…

A modular reduced-order modeling strategy for coupled multiphysics problems

Since most modern industrial systems involve interactions between multiple physical phenomena (e.g., mechanical, thermal, or electromagnetic), their high-fidelity simulation requires accounting for their multiphysical behavior [1]. Whenever the…

A new physics-guided data assimilation framework for online structural monitoring: application to shaking table tests

The modified Constitutive Relation Error (mCRE) is a model updating functional whose physics-based construction avoids the explicit dependency into a priori user’s expertise. Its robustness to measurement noise and remarkable convexity properties…

Towards a model-order reduction strategy for nonlinear dynamics parametric simulations

Assessing the risk of failure of a structure subjected to seismic hazard often requires numerous costly computations. When computing fragility curves, for instance, the nonlinear damageable behaviour of structures needs to be considered, and the…
