    • A data-driven temperature compensation approach for Structural Health Monitoring using Lamb waves 
      Article dans une revue avec comité de lecture
      FENDZI, Claude; COFFIGNAL, Gérard; ccMECHBAL, Nazih; ccGUSKOV, Mikhail; ccRÉBILLAT, Marc (SAGE Publications (UK and US), 2016)
      This paper presents a temperature compensation method for Lamb wave structural health monitoring. The proposed approach considers a representation of the piezo-sensor signal through its Hilbert transform that allows one ...
    • Texture and Lattice Distortion Study of an Al-6061-T6 Alloy Produced by ECAP 
      Article dans une revue avec comité de lecture
      RUIZ, Carlos Reyes; FIGUEROA, Ignacio A.; CABRERA, José M.; ISMELI, Alfonso; GONZALEZ, Gonzalo; ccBRAHAM, Chedly (Nihon Kinzoku Gakkai, 2015)
      Equal channel angular pressing (ECAP) is a severe plastic deformation (SPD) technique that produces nanostructured materials. Based on a remarkable grain size reduction, this process has led to improve mechanical properties, ...
    • Modeling laser drilling in percussion regime using constraint natural element method 
      Article dans une revue avec comité de lecture
      ILLOUL, Lounès; ccLORONG, Philippe; ccRANC, Nicolas; ccSCHNEIDER, Matthieu; ccFAVIER, Véronique; ccGIRARDOT, Jeremie (Springer Verlag, 2015)
      The laser drilling process is the main process used in machining procedures on aeronautic engines, espe- cially in the cooling parts. The industrial problematic is to reduce geometrical deviations of the holes and defects ...
    • From nonlinear system identification to structural health monitoring 
      Conférence invitée
      ccRÉBILLAT, Marc (2016)
      The process of implementing a damage monitoring strategy for aerospace, civil and mechanical engineering infrastructure is referred to as structural health monitoring (SHM) and implies a sensor network that monitors the ...
    • Experimental studies of Portevin-Le Chatelier plastic instabilities in carbon-manganese steels by infrared pyrometry 
      Article dans une revue avec comité de lecture
      DU, W; RANC, I; WAGNER, D; ccRANC, Nicolas (Elsevier, 2016)
      The dynamic strain aging (DSA) phenomenon that occurs in some materials under certain temperature and strain rate conditions can cause plastic strain localization in the form of Portevin-Le Chatelier (PLC) bands. ...
    • Laser-delayed double shock-wave generation in water-confinement regime 
      Article dans une revue avec comité de lecture
      COURAPIED, Damien; BERTHE, Laurent; PEYRE, Patrice; COSTE, Frédéric; ZOU, J-P; SAUTIVET, A.-M. (Laser Institute of America, 2015)
      This paper investigates the different physical processes involved during laser-delayed double shock-wave generation in water-confined geometry. With this technique, two laser pulses, separated by a Δt duration, irradiate ...
    • Validation and verification of FE models of piezo based SHM systems 
      Communication avec acte
      BALMES, Etienne; BIANCHI, Jean-Philippe; ccGUSKOV, Mikhail (2016)
      The idea of generating and sensing Lamb waves through piezoelectric sensor/actuator configurations is common for Structural Health Monitoring (SHM) applications. Methods using time of flight analysis require the prediction ...
