On the implementation of a nonlinear shell-based SPH method for thin multilayered structures

Jun Lin, Hakim Naceur, Abdel Laksimi, Daniel Coutellier

An efficient Smoothed Particle Hydrodynamics method is developed in this paper for bending and buckling analysis of laminated composite plates and shells. The governing differential equations of thin structures is based on the First-order Shear Deformation Theory considering the geometrically…

The Impact of Natural Disasters on Critical Infrastructures: A Domino Effect-based Study

Farid Kadri, B. Birregah, Eric Chatelet

Recent events show a significant increase in the number of disasters with natural and/or technological causes, which could have potentially serious consequences for critical infrastructures. Were these infrastructures to fail or be destroyed, the resulting cascade effect (chain of accidents) could…

L’aide à la décision comme cadre de gouvernance-innovation, Decision aiding as a framework of governance-innovation

Igor Crevits, Laurence Bonnafous, Said Hanafi

Dans cet article, nous avançons quelques arguments montrant que l’aide à la décision est utile pour soutenir une démarche d’innovation. Les concepts de l’aide à la décision permettent de caractériser finement une innovation, en la reliant à l’existant, comme une évolution et non comme une rupture.…, In this paper, we propose some arguments showing that decision aiding is useful for supporting an innovation approach. The concepts of decision aiding allow to finely characterize innovation, by linking it to the current situation, as an evolution rather than a disruption. The methodological…

How to Select the Most Relevant 3D Roughness Parameters of a Surface

Raphaël Deltombe, Krzysztof Kubiak, Maxence Bigerelle

In order to conduct a comprehensive roughness analysis, around sixty 3D roughness parameters are created to describe most of the surface morphology with regard to specific functions, properties or applications. In this paper, a multiscale surface topography decomposition method is proposed with…

Higher-Order Sliding Mode Observer for Speed and Position Estimation in PMSM

Suneel Kumar Kommuri, Kalyana Chakravarthy Veluvolu, Michael Defoort, Yeng Chai Soh

This paper presents a speed and position estimation method for the permanent magnet synchronous motor (PMSM) based on higher-order sliding mode (HOSM) observer. The back electromotive forces (EMFs) in the PMSM are treated as unknown inputs and are estimated with the HOSM observer without the need…

Current configuration detection in hybrid systems: Application to a conjunction–disjunction mechatronics system

Fayssal Arichi, Cherki Brahim, Mohamed Djemai

This paper deals with the problem of detecting the current configurations of hybrid mechatronic systems, where theevolution of the discrete part is governed by a Petri net. The considered class of systems may have several subsystems,with different dimensions, evolving at the same time. The current…

Active modes and switching instants identification for linear switched systems based on Discrete Particle Swarm Optimization

Sahbi Boubaker, Mohamed Djemai, Noureddine Manamanni, Faouzi M'Sahli

n this paper, a methodology for identifying switching sequences and switching instants of switched linear systems (SLS) is derived. The identification problem of a SLS is a challenging and non-trivial problem. In fact, it involves interaction between binary, discrete and real-valued variables. A…

Roughness statistical influence on cell adhesion using profilometry and multiscale analysis

Sylvain Giljean, Maxence Bigerelle, Karine Anselme

In this study, two series of 11 samples of TiAl6V4 titanium alloy and 316L stainless steel have been polished in an isotropic manner at different levels in order to quantify the influence of biomaterial roughness on cell behavior. Topography was measured by a tactile profilometer and a multiscale…
