Experimental characterisation of multi-sheet, multi-material spot-welded assemblies under pure and combined I/II loading conditions

Rim Chtourou, Fahmi Chaari, Grégory Haugou, Nicolas Leconte, Eric Markiewicz, Bassem Zouari

Resistance spot welding (RSW) of multiple sheets (more than two) and combining multiple materials (i.e. different steel grades) are increasingly employed with the growing demand of safety and lightweight vehicle structures. Despite that, the mechanical strength and rupture of such a new generation…, Une nouvelle génération d’assemblages trois tôles multi-matériaux soudés par point a été récemment introduite dans la conception de la caisse en blanc des véhicules automobiles, pour améliorer la sécurité et contribuer également à l’allégement structural. Malgré l’utilisation croissante de ces…

Quantitative analysis of galling in cold forging of a commercial Al-Mg-Si alloy

Kevin Le Mercier, Mirentxu Dubar, Katia Mocellin, André Dubois, Laurent Dubar

Multiple upsetting-sliding tests are performed at sliding velocities in the range of 20-200 mm.s-1 and at different plastic deformations to reproduce the local contact conditions experienced at the tool/workpiece interface during cold forging of a 6082 aluminium alloy. An original approach, able to…

A heuristic hybrid framework for vector job scheduling

Nareyus I Lawrance Amaldass, Cormac Lucas, Nenad Mladenovic

We examine the first phase of a known NP-hard 2-stage assembly problem. It consists of sequencing a set of jobs having multiple components to be processed. Each job has to be worked on independently on a specific machine. We consider these jobs to form a vector of tasks. Our objective is to…

Asymptotically necessary and sufficient conditions for Takagi–Sugeno models using generalized non-quadratic parameter-dependent controller design

Raymundo Márquez Borbόn, Thierry-Marie Guerra, Miguel Bernal, Alexandre Kruszewski

Results in this paper generalize recent approaches on non-quadratic controller design for Takagi–Sugeno models based on a matrix transformation. Conditions thus obtained depend on a single parameter which allows an efficient search of feasible solutions via linear matrix inequalities; moreover,…

Refinements of some Pachpatte and Bihari inequalities on time scales

Bacem Ben Nasser, Khaled Boukerrioua, Michael Defoort, Mohamed Djemai, Mohamed Ali Hammami

In this study, some generalizations and refinements of some inequalities of Pachpatte and Bellman-Bihari types are established on arbitrary time domains using the time scale theory. The obtained results unify continuous and discrete inequalities and extend some results known in the literature. The…

Towards increased systems resilience: New challenges based on dissonance control for human reliability in Cyber-Physical&Human Systems

Frédéric Vanderhaegen

This paper discusses concepts and tools for joint human and cyber-physical-systems analysis and control in the view of increasing the whole system resilience. More precisely, it details new challenges for human reliability based on dissonance control of Cyber-Physical&Human Systems (CPHS) to…

Design exploration of efficient implementation on SoC heterogeneous platform: HEVC intra prediction application

Manel Kammoun, Ahmed Ben Atitallah, Rabie Ben Atitallah, Nouri Masmoudi

The relationship between CPU and hardware accelerator is critical especially in some systems that require intensive tasks and large amount of data to deal with such as video coding systems. This cooperation provides significant improvements in run-time speed and power consumption. As software (SW)…
