    • Advanced solid elements for sheet metal forming simulation 

      Mataix, Vicente; Rossi, Riccardo; Oñate Ibáñez de Navarra, Eugenio; Flores, Fernando G (Institute of Physics (IOP), 2016)
      Text en actes de congrés
      Accés obert
      The solid-shells are an attractive kind of element for the simulation of forming processes, due to the fact that any kind of generic 3D constitutive law can be employed without any additional hypothesis. The present work ...

    • Enhanced rotation-free basic shell triangle for sheet stamping problems 

      Oñate Ibáñez de Navarra, Eugenio; Flores, Fernando G; Neamtu, L.; Weiler, R.; Rojek, Jerzy; Zárate Araiza, José Francisco (2004)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      An enhanced version of the rotation-free three node triangular BST shell element for sheet stamping analysis is presented. The original BST element is based on an assumed constant curvature field expressed in terms of the ...

    • Enhanced rotation-free basic shell triangle: applications to sheet metal forming 

      Oñate Ibáñez de Navarra, Eugenio; Flores, Fernando G; Neamtu, L. (Springer, 2005)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      An enhanced rotation-free three node triangular shell element (termed EBST) is presented. The element formulation is based on a quadratic interpolation of the geometry in terms of the six nodes of a patch of four triangles ...

    • Formulation of solid-shell finite elements with large displacements considering different transverse shear strains approximations 

      Flores, Fernando G; Nallim, Liz G.; Oller Martínez, Sergio Horacio (2017-08)
      Article
      Accés obert
      This work presents a general formulation and implementation in solid-shell elements of the refined zigzag theory and the trigonometric shear deformation theory in an unified way. The model thus conceived is aimed for use ...
