    • Determination of the characteristic parameters of tension-compression asymmetry of Shape Memory Alloys using full-field measurements 
      Conférence invitée
      CHEMISKY, Yves; ECHCHORFI, Rachid; BOURGEOIS, Nadine; PIOTROWSKI, Boris; ccMERAGHNI, Fodil (Trans Tech publications, 2013)
      In this work, a method for the identification of the transformation surface of Shape Memory Alloys based on full field measurements is presented. An inverse method coupled with a gradient-based algorithm has been developed ...
    • On the elasto-viscoplastic behavior of the Ti5553 alloy 
      Article dans une revue avec comité de lecture
      ccBEN BETTAIEB, Mohamed; VAN HOOF, Thibaut; PARDOEN, Thomas; DUFOUR, Philippe; LENAIN, Astrid; JACQUES, Pascal J.; HABRAKEN, Anne-Marie (Elsevier, 2014)
      The elastoviscoplastic behavior of the Ti5553 alloy is characterized and compared to the classical Ti–6Al–4V alloy. The true stress–strain curves are determined based on tensile tests performed under different strain rates ...
    • Identification and interpretation of material parameters of a shape memory alloy (SMA) model 
      Conférence invitée
      PIOTROWSKI, Boris; CHEMISKY, Yves; ECHCHORFI, Rachid; BOURGEOIS, Nadine; PATOOR, Etienne; ccMERAGHNI, Fodil (Trans Tech Publications, 2013)
      The thermomechanical behavior of Shape Memory Alloys (SMAs) is described by many micromechanical and phenomenological models. The first ones have material parameters whose physical meaning is based on the crystallography ...
    • Micro and macroscopic characterization of A-SMC under high speed tensile test 
      Conférence invitée
      SHIRINBAYAN, Mohammadali; SUROWIEC, Benjamin; BOCQUET, Michel; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph; ccMERAGHNI, Fodil (2015)
      Advanced Sheet Molding Compound (A-SMC) is a serious composite material candidate for structural automotive parts. It has a thermoset matrix and consists of high weight content of glass fibers (50% in mass) compared to ...
    • Identification of Model Parameter for the Simulation of SMA Structures Using Full Field Measurements 
      Conférence invitée
      CHEMISKY, Yves; BOURGEOIS, Nadine; CORNELL, Stephen; ECHCHORFI, Rachid; PATOOR, Etienne; ccMERAGHNI, Fodil (Ibrahim Karaman, Raymundo Arróyave and Eyad Masad/ Wiley, 2015)
      With the design of new devices with complex geometry and to take advantage of their large recoverable strains, shape memory alloys components (SMA) are increasingly subjected to multiaxial loadings. The development process ...
    • Linearization and implementation of venu model in small strain theory for polyamide 6.6 
      Conférence invitée
      ANAGNOSTOU, Dimitrios; CHATZIGEORGIOU, George; BOUVARD, Jean-Luc; CHEMISKY, Yves; BILLON, Noelle; ccMERAGHNI, Fodil (2016)
      The so-called VENU model is a visco-hyperelastic constitutive model, designed for amorphous rubbery polymers, which is based on an original approach initially developed by N. Billon (J. Appl. Polym. Sci. 125:4390-4401, ...
    • Effective properties of dissipative composites under fully coupled thermomechanical processes 
      Conférence invitée
      CHATZIGEORGIOU, George; CHARALAMBAKIS, Nicolas; CHEMISKY, Yves; ccMERAGHNI, Fodil (2016)
      The current work deals with periodic composite media undergoing fully coupled thermomechanical loading. In these composites the material constituents are considered to obey the generalized standard materials laws. The aim ...
