    • Numerical simulation of sheet metal forming using anisotropic strain-rate potentials 
      Article dans une revue avec comité de lecture
      RABAHALLAH, Meziane; BOUVIER, Salima; BACROIX, Brigitte; ccBALAN, Tudor (Elsevier, 2009)
      For numerical simulation of sheet metal forming, more and more advanced phenomenological functions are used to model the anisotropic yielding. The latter can be described by an adjustment of the coefficients of the yield ...
    • Assumed-strain solid–shell formulation for the six-node finite element SHB6: evaluation on nonlinear benchmark problems 
      Conférence invitée
      ccABED-MERAIM, Farid; TRINH, Vuong-Dieu; COMBESCURE, Alain (2011)
      Because accuracy and efficiency are the main features expected within the finite element (FE) method, the current contribution proposes a six-node prismatic solid–shell, denoted (SHB6). The formulation is extended here to ...
    • Vibration modeling of sandwich structures using solid-shell finite elements 
      Communication avec acte
      KPEKY, Fessal; BOUDAOUD, Hakim; ccCHALAL, Hocine; ccABED-MERAIM, Farid; DAYA, El Mostafa (2014)
      The aim of this work is to propose a new finite element modeling for vibration of sandwich structures with soft core. Indeed, several approaches have been adopted in the literature to accurately model these types of ...
    • Validation d’une nouvelle version de l’élément solide/coque “SHB8PS” sur des cas tests non linéaires 
      Communication avec acte
      ccABED-MERAIM, Farid; COMBESCURE, Alain (2007)
      L’intérêt de disposer d’éléments finis volumiques capables de modéliser des structures minces est motivé par de nombreux problèmes industriels. Ainsi, ces dernières années, plusieurs travaux ont été réalisés dans ce domaine. ...
    • Review and Perspectives: Shape Memory Alloy Composite Systems 
      Article dans une revue avec comité de lecture
      LESTER, Brian; BAXEVANIS, Theocaris; CHEMISKY, Yves; LAGOUDAS, Dimitris (Springer Verlag, 2015)
      Following their discovery in the early 60's, there has been a continuous quest for ways to take advantage of the extraordinary properties of shape memory alloys (SMAs). These intermetallic alloys can be extremely compliant ...
    • Elastic-plastic ductile damage model based on strain-rate plastic potential 
      Article dans une revue avec comité de lecture
      CAZACU, Oana; ccBALAN, Tudor (Elsevier, 2013)
      Modeling of ductile damage is generally done using analytical potentials, which are expressed in the stress space. In this paper, for the first time it is shown that strain rate potentials which are exact conjugate of the ...
    • Study of elementary micro-cutting in hardened tool steel 
      Communication avec acte
      PIQUARD, Romain; GILBIN, Alexandre; FONTAINE, Michaël; ccALAIN, D'acunto; THIBAUD, Sébastien; DUDZINSKI, Daniel (Czech Machine Tool Society, 2014)
      In order to model micro-milling cutting forces, a way is to apply a local model on discretized elements of the cutting edge and then summing on the whole edge to obtain the global cutting forces. This local model is usually ...
