Numerical Hybrid Fluid Structure Coupling: Application to Mixed Lubrication in Metal Forming

Raphaël Deltombe, Anastasia Belotserkovets, Laurent Dubar

The present paper deals with a sequential fluid structure coupling approach in order to solution the roughness prediction. The cold rolling model involves the strip with its asperities, the lubricant and the working roll. The strip asperities are modeled in 2D (trapezoidal shape) forming valleys…

Tailoring polylactide (PLA) properties for automotive applications: Effect of addition of designed additives on main mechanical properties

Delphine Notta-Cuvier, Jérémy Odent, Rémi Delille, Marius Murariu, Franck Lauro, Jean-Marie Raquez, Bruno Bennani, Philippe Dubois

Among currently available bio-based polymers, poly(lactic acid) (PLA) has interesting physical and mechanical properties (high tensile strength and stiffness, good processability and biodegradability) but relatively low thermal stability, low toughness and is extremely brittle, all of which can be…

Nested backward compensation of unmatched perturbations via HOSM observation

Alejandra Ferreira de Loza, E. Punta, Leonid Fridman, Georgio Bartolini, Sebastien Delprat

This paper tackles the compensation problem of linear time invariant systems affected by unmatched perturbations. The proposed methodology exploits a high order sliding mode observer, guaranteeing theoretically exact state and perturbation estimation. A compensation based strategy is proposed to…

Numerical Study of Convective Heat Transfer Enhancement in a Pipe Rotating Around a Parallel Axis

Aurélie Fasquelle, Julien Pellé, Souad Harmand, Igor V. Shevchuk

Cooling of electrical machines is nowadays of high interest in order to improve their efficiency. In railway applications, electrical motors can be shrouded in order to avoid particles to be deposited inside. To ensure a satisfactory cooling, pipes are placed inside the rotor and are thus rotating…

Thermo-Mechanical Behaviour of Spheroidal Graphite Iron

Kevin Le Mercier, Michel Watremez, Laurence Fouilland, Jean-Dominique Guerin, Laurent Dubar

The main objective of this paper is to identify the thermo-mechanical behaviour of the spheroidal graphite (SG) iron EN-GJS-700. In the first instance, compression tests are carried out using Gleeble 3500 system enabling a precise control on testing temperature and strain rate. The effects of these…

Chronic ankle instability (CAI) characterization with analysis of various balance tasks

Raphaël Pionnier, Nicolas Decoufour, Christophe Popineau, Emilie Simoneau-Buessinger

Background.– Chronic ankle instability (CAI), characterized by recurrent episodes of lateral instability [3], is a complication of lateral ankle sprain which is the most common injury in sport activities [1]. Static balance can be evaluated in bipodal and unipodal conditions, and dynamic balance…

Heat transfer of Cu–water nanofluid in an enclosure with a heat sink and discrete heat source

Hamdy Hassan

Heat transfer inside horizontal and vertical enclosure filled with Cu-water nanofluid is studied. A heat sink with rectangular fins represents the base plate of the enclosure where it is heated by a discrete heat source at the bottom of the heat sink. The front face of the heat sink is kept at…

Identification of Friction Law to Model Orthogonal Cutting

Yannick Senecaut, Michel Watremez, Julien Brocail, Laurent Dubar

A first approach of tool-chip interface behaviour for high-speed machining modelling has been carried out by Al Brocail and 2010 and an empirical friction law has been first determined. This law has been established for high temperatures (initial sample temperature equal to 750 K) and low sliding…

Balance control in gait children with cerebral palsy

Laura Wallard, Gilles Dietrich, Yves Kerlirzin, Jonathan Bredin

This study sought to highlight the balance control process during gait in children with cerebral palsy (CP) by analyzing the different strategies used in order to generate forward motion while maintaining balance. Data were collected using a motion analysis system in order to provide a clinical…
