Analyse incrémentale basée sur les résolutions alternées pour la modélisation d'endommagement et la rupture fragile par champ de phase

Thanh Hai Tuan Tran, Jamila Rahmoun, Hakim Naceur, Djimédo Kondo

Dans cette étude, nous proposons une technique numérique de champ de phase pour la modélisation de l’endommagement de structures. Cette approche incrémentale est basée sur une résolution alternée des variables cinématiques et d’endommagement à chaque pas. La condition d’irréversibilité d’…

Managing demand volatility of pharmaceutical products in times of disruption through news sentiment analysis

Angie Nguyen, Robert Pellerin, Samir Lamouri, Béranger Lekens

Unplanned events such as epidemic outbreaks, natural disasters, or major scandals are usually accompanied by supply chain disruption and highly volatile demand. Besides, authors have recently outlined the need for new applications of artificial intelligence to provide decision support in times of…

Robust flight control for a quadrotor under external disturbances based on predefined-time terminal sliding mode manifold

Moussa Labbadi, Kamal Elyaalaoui, Mohamed Amine Dabachi, Soufian Lakrit, Mohamed Djemai, Mohamed Cherkaoui

This paper investigates the terminal sliding-mode control (TSMC) with predefined-time stability (PTS) for a disturbed quadrotor system (DQS). First, for both the rotational and translational subsystems of the DQS, a novel notion of predefined-time terminal sliding-mode manifold (PTTSMM) is created…

Toward a Reliable Estimation of Fluid Concentration using High Frequency Acoustic Waves: A Machine Learning Approach

Venu Babu Thati, Ibrahim Zaaroura, Malika Toubal, Nikolay Smagin, Souad Harmand, Julien Carlier, Ihsen Alouani

Using acoustic waves to estimate fluid concentration is a promising technology due to its practicality and non-intrusive aspect, especially for medical applications. The existing approaches are exclusively based on the correlation between the reflection coefficient and the concentration. However,…

Robustness of specimen design criteria for identification of anisotropic mechanical behaviour from heterogeneous mechanical fields, Robustesse des critères de conception des éprouvettes pour l'identification de comportements anisotropes à partir de champs mécaniques hétérogènes

Jean-David Thoby, Thomas Fourest, Bertrand Langrand, Delphine Notta-Cuvier, Eric Markiewicz

To reduce the number of tests required to characterise anisotropic elastoplastic constitutive models, an approach is to design specimen geometries to diversify the stress states generated in a single test. The experiments are then processed using an inverse identification method based on full-field…, Pour réduire le nombre d'essais nécessaires à la caractérisation des modèles élasto-plastiques anisotropes, une approche consiste à concevoir des géométries d'éprouvettes permettant de diversifier les états de contrainte générés dans un seul essai. Les essais sont ensuite traités à l…

Nondestructive evaluation of composite and porous materials by 3D acoustical imaging

Wei-Jiang Xu, Franck Lauro, Lynda Chehami, Hervé Morvan, Rémi Delille

In this work, based on the use of high frequency (20MHz) focus ultrasonic transducer and echography, a high-resolution three-dimensional acoustical imaging technique has been developed, permitting 3D reconstruction of the internal structure of materials at mesoscopic level. The data acquisition is…
