Design of a pre-stretched tension Hopkinson bar device: Configuration, tail corrections, and numerical validation

Grégory Haugou, Nicolas Leconte, Hervé Morvan

The use of Hopkinson bar device is suitable for the characterization of high ductility metallic alloys up to fracture at moderate strain rates. Since a fairly long duration time is required, the pre-stretched technique has been chosen. However, elastic wave overlapping at strain gauges is common…

Stabilité assise chez les personnes avec lésion médullaire

Mathias Blandeau, Ciska Molenaar, Víctor Estrada Manzo, Thierry-Marie Guerra, Philippe Pudlo, François Gabrielli

</br>Introduction</br> Nous présentons une technique de modélisation pour estimer des paramètres du contrôle de la stabilité posturale en position assise chez les sujets souffrant de lésion médullaire. La position assise sans soutien dorsal est souvent pratiquée chez les personnes…

Méthode pour évaluer un arrêt non planifié lors de l’initiation de la marche

Anis Toumi, Sebastien Leteneur, Christophe Gillet, Franck Barbier, Paul Allard, Emilie Simoneau-Buessinger

Introduction La terminaison de la marche, planifiée (Roeing et al., 2015) ou non (Jung et al., 2016), peut être utilisée afin de perturber la stabilité posturale d’une personne. L’objectif de cette étude est de présenter une méthode pour évaluer l’impact d’un arrêt soudain lors de l’initiation de…

Liquid film evaporation inside an inclined channel: Effect of the presence of a porous layer

Amine Terzi, Walid Foudhil, Souad Harmand, Sadok Ben Jabrallah

In this paper, we numerically investigate the improvement of the heat and mass transfer during the evaporation of a liquid film by introducing a liquid saturated porous layer inside an inclined channel. To achieve this, we solved the non linear partial differential equations that describe the…

Solder fatigue failures in a new designed power module under Power Cycling

Camille Durand, Markus Klingler, Maxence Bigerelle, Daniel Coutellier

Today a point has been reached where lifetimes of power modules are limited by the standard packaging technologies, such as wire bonding. To surpass these limits, a new power module was designed using Cu clips as interconnects instead of Al wire bonds. With this new design the structure robustness…

Hand use during the lift phase of parallel sitting transfers of two spinal cord injured subjects

Ciska Molenaar, François Gabrielli, Mathias Blandeau, Philippe Pudlo

The purpose of this study is to list the shapes and locations used by both hands of spinal cord injured people during parallel transfers. Two spinal cord injured subjects were filmed while realizing 24 transfers each in a reconstructed aircraft cabin. An observation grid was developed to analyze…

Impact of spatial hindrance on sit-to-stand and exit strategies of low mobility passengers

François Gabrielli, Ciska Molenaar, Mathias Blandeau, Philippe Pudlo

Aircraft cabin is considered as a hostile environment for low mobility passengers, especially around seat interaction. Improving air travel experience, and more specifically sit-tostand (STS) and seat exit could be done through digital human modeling, and there is a need for a first description of…

Modelling seated postural stability for complete spine cord injury

Mathias Blandeau, Thierry-Marie Guerra, Philippe Pudlo, François Gabrielli, Víctor Estrada Manzo

This paper introduces a modelling approach to investigate seated postural stability for subject suffering a complete spine cord injury (SCI). A mechanical model, variation of the double inverted pendulum, is used to represent a subject in the sagittal plane moving back and forth his uppers limbs…

Integration of Subjective and Objective Usability Evaluation Based on IEC/IEC 15939: A Case Study for Traffic Supervision Systems

Ahlem Assila, Káthia Marçal de Oliveira, Houcine Ezzedine

Usability evaluation for interactive systems is one of the greatest interests for Human-Computer Interaction community. To support this evaluation, several subjective and objective methods have been proposed and applied in academy and industry. In this context, usability evaluators usually work…

Simulation of continuum electrical conduction and Joule heating using DEM domains

Cédric Hubert, Damien Andre, Laurent Dubar, Ivan Iordanoff, Jean-Luc Charles

This paper proposes an original method to simulate the electrical conduction in continuums with the Discrete Element Method (DEM). The proposed method is based on the graphs theory applied to electrical resistance network, where the resistance between two discrete elements is estimated through the…
