Effect of initial grain size on the mechanical behaviour of austenite during deformation under hot-working conditions

Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, José Gregorio La Barbera-Sosa, Mirentxu Dubar, Laurent Dubar

The present investigation has been conducted to study the effect of the austenitic grain size (AGS) on the flow stress behaviour of austenite, deformed in a wide range of temperatures and strain rates, employing samples of a commercial ER7 steel grade. To accomplish this objective, a novel general…

Simultaneous Estimation of State and Unknown Input for TS Fuzzy Systems with Unmeasured Premise Variables

Jun-Tao Pan, Tran Anh-Tu Nguyen, Thierry-Marie Guerra, Jimmy Lauber, Weiwei Zhang

Designing unknown input (UI) observers for Takagi-Sugeno (TS) fuzzy systems is known as a challenging issue, especially when the premise variables are unmeasured. This paper presents a new approach to deal with unmeasured premise variables in UI observer design for discrete-time TS fuzzy systems.…

Nonlinear Convex Control Design for Differential Algebraic Equation Systems via LMIs

Juan Carlos Arceo Luzanilla, Jimmy Lauber

This document presents an approach for nonlinear control design in singular systems by combining Lyapunov's direct method with exact convex structures. The conditions obtained are given in terms of linear matrix inequalities, the methodology proposed is illustrated by applying the nonlinear…

A Comprehensive Approach for Camera/LIDAR Frame Alignment

Mokhtar Bouain, Denis Berdjag, Nizar Fakhfakh, Rabie Ben Atitallah

This paper deals with the initial phase of any multi-sensor acquisition, the sensor alignment process. We focus on extrinsic calibration of vision-based and line scan LIDAR sensors for automotive application. We investigate two research approaches for the calibration process: analytical and numeric…

Numerical and Experimental Study of Flow and Convective Heat Transfer on a Rotor of a Discoidal Machine With Eccentric Impinging Jet

Chadia Haidar, Rachid Boutarfa, Mohamed Sennoune, Souad Harmand

Abstract Discoidal rotor–stator systems are especially used in rotating machines and in numerous industrial applications. The design of high-power machine requires compliance with certain cooling-related stresses. Using an air jet impinging on a rotating disk is one way to increase the global heat…

Robust Feedback Linearization Approach for Fuel-Optimal Oriented Control of Turbocharged Spark-Ignition Engines

Tran Anh-Tu Nguyen, Thierry-Marie Guerra, Jimmy Lauber

This chapter proposes a new control approach for the turbocharged air system of a gasoline engine. To simplify the control implementation task, static lookup tables (LUTs) of engine data are used to estimate the engine variables in place of complex dynamical observer and/or estimators. The…

90° ferroelectric domain switching effect on interfacial strain mediated magnetoelectric coupling

Tarik Sadat, Damien Faurie, Pierre Godard, Dominique Thiaudière, Pierre-Olivier Renault, Fatih Zighem

The phenomena associated with strain-mediated multiferroic behavior have been quantitatively studied by combining synchrotron x-ray diffraction (XRD), ferromagnetic resonance (FMR) and macroscopic strain measurements (digital image correlation) in a magnetoelectric composite (Ni film on PZT…

Friction Correction of Austenite Flow Stress Curves Determined under Axisymmetric Compression Conditions

Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, José Gregorio La Barbera-Sosa, Juan Carlos Álvarez-Hostos, Philippe Moreau, Mirentxu Dubar, Laurent Dubar

The experimental flow stress curves of structural steels obtained from axisymmetric compression tests conducted under hot-working conditions very often include the frictional effects present at the tool/specimen interface. Such effects have a significant influence on the flow stress and therefore,…
