Modeling and characterization of bonded joints at high strain rates, Modélisation et caractérisation des joints collés à hautes vitesses de déformation

Benjamin Bourel, Grégory Haugou, Franck Lauro, Raphaël Deltombe, Denis Lesueur, Bruno Bennani

This paper deals with the modeling of bonded joints for structures subjected to dynamic crash loading. This new model based on a cohesive element takes into account the viscoelastic behavior, the damage and the failure of the adhesive. Due to the strain rate sensitivity, the identification of…, Ce papier traite de la modélisation de joints collés pour les structures soumises à des sollicitations de type crash. Cette nouvelle modélisation basée sur un élément cohésif tient compte du comportement viscoplastique, de l'endommagement ainsi que de la rupture de l'adhésive. Sensible à…

Large-Eddy simulation of turbulent heat transfer in pipe flows with respect to Reynolds and Prandtl number effects.

Meryem Ould-Rouiss, M. Bousbai, A. Mazouz

Heat transfer in a fully developed turbulent pipe flow is investigated by use of the large eddy simulation technique. Isoflux condition is imposed at the wall. Four Prandtl numbers are considered (0.71,3,5,7) and three Reynolds numbers (5500, 10000, 20000). The effects of Reynolds and Prandtl…

Methods for Designing Tangible UI: A First Comparative Case Study

Céline Coutrix, Guillaume Rivière, Katarzyna Borgiel, Julien Castet, Nadine Couture, Brygg Ullmer, Jens Geelhaar, Patrick Reuter, Nawel Takouachet, Christophe Kolski, Sophie Lepreux, Jérémy Legardeur, Sébastien Kubicki, Yvonne Jansen, Amira Bouadid

In this work-in-progress, we present early comparative experiences with methods for designing tangible user interfaces (TUIs). Groups of designers used different approaches for design in the context of a concrete case study: a TUI for controlling LED lighting within hotel rooms. From the results of…

Natural convection heat transfer of nanofluids along a vertical plate embedded in porous medium

Ziya Uddin, Souad Harmand

The unsteady natural convection heat transfer of nanofluid along a vertical plate embedded in porous medium is investigated. The Darcy-Forchheimer model is used to formulate the problem. Thermal conductivity and viscosity models based on a wide range of experimental data of nanofluids and…

Thermal Optimization of a High Power Salient-Pole Alternator

Augusto Bornschlegell, Julien Pellé, Souad Harmand, Aurélie Fasquelle, Jean-Pierre Corriou

An optimization of the thermal behavior of a high-power salient-pole electrical machine is presented. Temperatures are calculated with the lumped method, which provides the thermal trends with relatively low computational cost. This model is used to define an aggregated objective function of our…

Open-People: Open Power and Energy Optimization PLatform and Estimator

Eric Senn, Daniel Chillet, Olivier Zendra, Cécile Belleudy, Sebastien Bilavarn, Rabie Ben Atitallah, Christian Samoyeau, Agnès Fritsch

Designing low power complex embedded systems is now a critical challenge for a large number of electronic corporations. Low power is generally critical due to its impact on lifetime, battery longevity, battery capacity, temperature constraints, etc. Unfortunately, when a designer needs some power…

Fault diagnosis and monitoring of oscillatory failure case in aircraft inertial system

Denis Berdjag, Jérome Cieslak, Ali Zolghadri

A method for oscillatory fault detection and isolation is presented and used to detect oscillatory failures of redundant aircraft sensors involved in the computation of flight control laws. The objective is to switch off the erroneous sensor and to compute a consolidated parameter using data from…

High order sliding mode control for hybrid vehicle stability

Sebastien Delprat, Alejandra Ferreira de Loza

This paper tackles the problem of driving stability for a hybrid vehicle. A rear electric motor has been added to the vehicle driveline and the positive/negative torque generated by this motor affects the driving conditions. The vehicle stability control is addressed using high order sliding modes…
