A Bloch analysis extended to weakly disordered periodic media

This paper develops an asymptotic method to predict the dispersion curves of a \rYL{weakly disordered} medium. The \rYL{disordered} coefficients of the original acoustic equation are related to periodic coefficients through a change of variables,…

Ferroelectric texture of individual barium titanate nanocrystals

Ferroelectric materials display exotic polarization textures at the nanoscale that could be used to improve the energetic efficiency of electronic components. The vast majority of studies were conducted in two dimensions on thin films, that can be…

On the benefits of a multiscale strategy to model-order reduction for frictional contact problems

In this work, the efficiency of a multiscale strategy based on a domain decomposition method (DDM) for model-order reduction of friction contact problems is presented. The resolution strategy is based on the LATIN method combined with the Proper…

Damage detection and quantification via multiview DIC at varying scales

Background: To minimize measurement uncertainties and create seamless procedures between tests and simulations for the characterization and prediction of damage in large scale structures, a system capable of monitoring the quantities of interest at…

The Unstable Fracture of Multifilament Tows

The present paper investigates the unexpected unstable failure observed commonly on fiber tows tensile-tested under strain-controlled loading, although the force on the fibers should theoretically be relaxed under controlled strain. A model of the…

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…
