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…

MIP formulations for identical parallel machine scheduling problem with single server

Abdelhak El Idrissi, Rachid Benmansour, Mohammed Benbrahim, David Duvivier

This paper considers the problem of scheduling a set of independent jobs on an arbitrary number of identical parallel machines with setup consideration and a makespan objective. The setup operations are performed by one available server. We propose two mixed integer programming (MIP) formulations…

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…
