    In this paper some results of a wide experimental program are presented and compared with some finite element solution of sheet metal forming problems using a viscous shell formulation.
  • The intrinsic time for the streamline upwind/Petrov-Galerkin formulation using quadratic elements 

    Codina, Ramon; Oñate Ibáñez de Navarra, Eugenio; Cervera Ruiz, Miguel (1992-01)
    Artículo

    In this paper the functions of the Péclet number that appear in the intrinsic time of the streamline upwind/Petrov-Galerkin (SUPG) formulation are analyzed for quadratic elements. Some related issues such as the computation ...
  • A non-linear finite element method on unstructured meshes for added resistance in waves 

    García Espinosa, Julio; Serván Camas, Borja (2018-06-15)
    Artículo
    Acceso abierto
    In this work a finite element method is proposed to solve the problem of estimating the added resistance of a ship in waves in the time domain and using unstructured meshes. Two different schemes are used to integrate the ...
  • Modeling polycrystalline materials with elongated grains 

    Pérez, Irvin; Muniz de Farias, Márcio; Castro, Manuel; Roselló, Roberto; Recarey Morfa, Carlos Alexander; Medina, Liosber; Oñate Ibáñez de Navarra, Eugenio (John Wiley & sons, 2019-04)
    Artículo

    A novel algorithm to reproduce the arrangement of grains in polycrystalline materials was recently published by the authors. In this original approach, a dense package of circles (or spheres) with the same distribution as ...
  • Propuesta para la futura norma de aislamiento sísmico de edificaciones en Colombia 

    Piscal Arévalo, Carlos Mario; López Almansa, Francisco (2018-10-01)
    Artículo
    Acceso abierto
    En Colombia no existe una normativa propia para el diseño de edificaciones con aislamiento sísmico de base; el limitado número de edificios aislados existentes en el país han sido diseñados según alguno de los documentos ...
