Morphology of Surface Integrity as Effect of Cold Forging of Aluminum Alloy

Catalin Pruncu, Tat Thang Pham, André Dubois, Mirentxu Dubar, Laurent Dubar

Aluminum and its alloys represent a common raw material for components released through a cold machining routine (i.e., forging, cold heading, and rolling processes). They offer easy manufacturing and high plastic strength, together with light weight, long life span, and easy recycling and are...

INFLUENCE OF THE BONE MORPHOLOGY ON MECHANICAL BEHAVIOR OF HUMAN SKULL FOR TWO STRAIN RATE CASES

Manaf Karkar, Christophe Maréchal, Rémi Delille, Grégory Haugou, François Bresson, Pascal Drazetic, Thomas Colard

Modeling the mechanical behavior of bone is very complex due to substantial variability of the mechanical response of bone. The objective of this study is to investigate the link between morphology of the human parietal bone and its mechanical behavior in compression with two different strain rates...

Matheuristics based on iterative linear programming and slope scaling for multicommodity capacitated fixed charge network design

Bernard Gendron, Said Hanafi, Raca Todosijević

We present new matheuristics for the multicommodity capacitated fixed-charge network design problem (MCND). The matheuristics are based on combining iterative linear programming (ILP) methods and slope scaling (SS) heuristics. Each iteration alternates between solving a linear program obtained by...

Design and Control of an Assistive Device for the Study of the Post-stroke Sit-To-Stand Movement

Benyamine Allouche, Amal Saadé, Antoine Dequidt, Laurent Vermeiren, Olivier Rémy-Néris

Every year more than 5 million people worldwide become hemiplegic as a direct consequence of stroke. This neurological deficiency, often leads to a partial or a total loss of standing up abilities and /or ambulation skills. In order to propose new supporting solutions lying between the wheelchair...

Efficient modeling of IEEE 802.11p MAC output process for V2X interworking enhancement

Fatma Salem, Yassin El Hillali, Smail Niar

Vehicle-to-anything (V2X) is a promising communication technology, which expected to revolutionise the ground transportation system by improving traffic safety and efficiency for people on roads. The future deployment of V2X requires interworking between different access technologies, i.e....

Virtual strain gauge based on a fuzzy discrete angular domain observer: Application to engine and clutch torque estimation issues

Rémi Losero, Jimmy Lauber, Thierry-Marie Guerra

In many real time applications, information of transmitted torque is a mandatory input of the embedded control strategies. In the most of cases, the use of a physical torque sensor (strain gauge) is compromised by cost and bulk reasons and the torque is not measured. Unfortunately, the need of an...

A New Construction of Optical Zero-Correlation Zone Codes

Benattou Fassi, Abdelmalik Taleb-Ahmed

A new method for constructing optical zero-correlation zone (OZCZ) codes based on the Hadamard matrix and the concatenation operation is proposed. The most important property of the obtained codes is that the periodic correlation function of the proposed codes is zero for the phase shifts within...

New environmentally friendly coatings for hot forging tools

André Dubois, Mirentxu Dubar, Colin Debras, Kurt Hermange, Christelle Nivot, Christian Courtois

Two alumina coatings are developed to protect tool surface in hot forging: pure γ-alumina matrix loaded with α-alumina particles and pure γ-alumina matrix loaded with h-BN particles. The coatings are deposited on stainless tools by using a sol-gel procedure. Adherent coatings are obtained with an...

Bending analysis of planar structures made of functionally graded material by a meshless method

Jiao Li, Jun Lin, Yanjin Guan, Guangchun Wang, Hakim Naceur

A meshless Smoothed Hydrodynamic Particle (SPH) model is established to simulate the bending deformation of 2D structures made of Functionally Graded Materials (FGMs). The material property is assumed to be varied continuously through the thickness direction according to the power-law distribution...
