Data-driven material modeling based on the Constitutive Relation Error

Prior to any numerical development, the paper objective is to answer first to a fundamental question: what is the mathematical form of the most general data-driven constitutive model for stable materials, taking maximum account of knowledge from…

Training an AI hyperelastic constitutive model with experimental data

A Physics-Augmented Neural network is trained to model a hyperelastic behavior. The dataset used for the training, validation, and test are displacement-force couples obtained from two experiments on a rubber-like material. One experiment was…

Approximation and definition of state variables for a comprehensive description of damage for ceramic matrix composites

Over the past decades, non-linear models describing damage and fracture of architectured materials have highly progressed, taking into account varied scenarios of degradation under complex multi-axial loadings. Many of these models remain expansive…

Identification et suivi de l'endommagement structural à l'aide de mesures expérimentales et d'une approche par filtre de Kalman modifié

Dans cette étude, une approche par filtre de Kalman modifié est appliquée en utilisant des données de déformation, obtenues par des capteurs à fibre optique à diffusion de Rayleigh lors d'un essai de flexion 4-points. l'objectif de cette approche…

OFDR optic fiber measurements: Performance limitations

As a part of the PhD research project, an OFDR Rayleigh-based optic fiber sensor is embedded as shown in a beam sample, passing through it 4 times to provide strain measurements along the axis of the fiber during a quasi-static 4-point bending test…
