Confinement device to assess dynamic crushability of wood material

Jérémy Wouts, Grégory Haugou, M. Oudjene, Hakim Naceur, Daniel Coutellier

Cellular materials such as wood are widely and advantageously used as shock absorbers in various transport applications. The design and manufacturing of structures made of these materials require the knowledge of their dynamic compressive properties at various strain rates and stress states.…

Towards the Numerical Prediction of Galling Onset in Cold Forming

Oussama Filali, André Dubois, Laurent Dubar, Mirentxu Dubar

Aluminum alloys are materials that have a strong tendency to galling when they are cold formed. Caused by a breakdown of the lubricant film between the part and the tool, galling can have dramatic consequences on the forming operation: scratches and cracks in the surface of the piece, clogging and…

Quantitative Evolution of WC-Co Cemented Carbide Tool Surface during the Cold Forming of Steel Parts

Laurent Dubar, Colin Debras, Mirentxu Dubar, André Dubois

The present paper investigates the evolution of the WC grain size and morphology with the number of produced parts. Four reduction dies used in cold forward extrusion of steel are taken from the production line: a brand new die and three dies which have respectively produced 100.000, 150.000 and…

Geometrically nonlinear bending analysis of functionally graded beam with variable thickness by a meshless method

Jun Lin, Jiao Li, Yanjin Guan, Guoqun Zhao, Hakim Naceur, Daniel Coutellier

Geometrically nonlinear bending deformation of Functionally Graded Beams (FGBs) with variable thickness is simulated by a meshless Smoothed Hydrodynamic Particle (SPH) method. The material properties of FGB is assumed to be varied smoothly in the thickness according to exponent-law distribution. To…

Correction to “Unknown input observer design for linear fractional-order time-delay systems” and a new enhanced LMI condition

Yassine Boukal, Mohamed Darouach, Michel Zasadzinski, Nour-Edine Radhy

This note considers the work entitled “Unknown Input Observer Design for Linear Fractional-Order Time-Delay Systems”. In the above paper [1], the authors gave the existence conditions of such observer, then based on the fractional order Lyapunov stability approach, a sufficient condition for the…

Decentralized motion planning and scheduling of AGVs in FMS

Guillaume Demesure, Michael Defoort, Abdelghani Bekrar, Damien Trentesaux, Mohamed Djemai

In this paper, decentralized motion planning and scheduling of automated guided vehicles (AGVs) in a flexible manufacturing system (FMS) is proposed. A motion planner is combined with a scheduler allowing each AGV to update its destination resource during navigation in order to complete the…

Modeling the viscoplastic flow behavior of a 20MnCr5 steel grade deformed under hot-working conditions, employing a meshless technique

Juan Carlos Álvarez-Hostos, Alfonso D. Bencomo, Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, Laurent Dubar

The present work has been conducted in order to develop a novel approach to predict the inhomogeneous flow of a 20MnCr5 steel during an axisymmetric hot compression test, by using the element-free Galerkin (EFG) method under a differential constitutive description. The governing equations have been…

Friction and Wear in Metal Forming: 25 Years at LAMIH UMR CNRS 8201

Laurent Dubar, André Dubois, Mirentxu Dubar

Since the beginning of the 90’s, research activities focused on friction and wear in metal forming have been developed at the LAMIH UMR CNRS 8201 in Valenciennes. Specific methodologies have been designed to optimize a given forming process (bulk forming process or sheet forming process). These…

Sarcopenia and Hip Structure Analysis Variables in a Group of Lebanese Postmenopausal Women

Riad Nasr, Eric Watelain, Antonio Pinti, Hayman Saddik, Ghassan Maalouf, Abdel Jalil Berro, César El Khoury, Ibrahim Fayad, Rawad El Hage

The aim of the present study was to compare hip structural analysis variables in postmenopausal women with sarcopenia and postmenopausal women with normal skeletal muscle mass index. This study included 8 postmenopausal women (aged between 65 and 84 years) with sarcopenia and 60 age-matched…
