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…

Computation of minimal covariants bases for 2D coupled constitutive laws

We produce minimal integrity bases for both isotropic and hemitropic invariant algebras (and more generally covariant algebras) of most common bidimensional constitutive tensors and -- possibly coupled -- laws, including piezoelectricity law,…
