      Huerta, Antonio; Díez, Pedro (Springer, 2016)
      Capítol de llibre

      Fernández Méndez, Sonia; Huerta, Antonio (2004-03)
      Article
      Accés obert
      Imposing essential boundary conditions is a key issue in mesh-free methods. The mesh-free interpolation does not verify the Kronecker delta property and, therefore, the imposition of prescribed values is not as straightforward ...

    • Locking in the incompressible limit for the element-free Galerkin method 

      Huerta, Antonio; Fernández Méndez, Sonia (Wiley and Sons, 2001-04)
      Article

      Volumetric locking (locking in the incompressible limit) for linear elastic isotropic materials is studied in the context of the element-free Galerkin method. The modal analysis developed here shows that the number of ...
    • Locking in the incompressible limit: pseudo-divergence-free element free Galerkin 

      Vidal Seguí, Yolanda; Villon, Pierre; Huerta, Antonio (2003-09)
      Article
      Accés obert
      Locking in finite elements has been a major concern since its early developments. It appears because poor numerical interpolation leads to an over-constrained system. This paper proposes a new formulation that asymptotically ...
