  • Fluid structure interaction by means of variational multiscale reduced order models 

    Tello Guerra, Alexis; Codina, Ramon; Baiges Aznar, Joan (2020-06)
    Article
    Restricted access - publisher's policy
    A reduced order model designed by means of a variational multiscale stabilized formulation has been applied successfully to fluid-structure interaction problems in a strongly coupled partitioned solution scheme. Details ...

  • Logarithmic conformation reformulation in viscoelastic flow problems approximated by a VMS-type stabilized finite element formulation 

    Moreno Martínez, Laura; Codina, Ramon; Baiges Aznar, Joan; Castillo, Ernesto (2019-09)
    Article
    Restricted access - publisher's policy
    The log-conformation reformulation, originally proposed by Fattal and Kupferman (2004), allows computing incompressible viscoelastic problems with high Weissenberg numbers which are impossible to solve with the typical ...

  • An experimentally validated study for open rib profiles steel-concrete composite slabs behavior in partial connection 

    Soltanalipour, Milad; Ferrer Ballester, Miquel; Marimón Carvajal, Federico (2019)
    Conference report
    Open Access
    In this paper the strength of steel deck-concrete composite slabs is studied. Conventional slabs with open and dovetail profiles are studied with different designs, galvanized and stainless steel. Partial connection method ...

    Oñate Ibáñez de Navarra, Eugenio; Zárate Araiza, José Francisco; Celigueta Jordana, Miguel Ángel; Miquel Canet, Juan; Carbonell, J.M.; Arrufat Garcia, Ferran; Latorre, Salvador; Santasusana Isach, Miquel; González Lopez, Jose Manuel (2017-05)
    External research report
    Open Access
    Abstract In this chapter we present recent advances in the Discrete Element Method (DEM) and in the coupling of the DEM with the Finite Element Method (FEM) for solving a variety of problems in non linear solid mechanics ...

  • Shockwaves in spillways with the particle finite element method 

    Salazar González, Fernando; San Mauro Saiz, Javier; Celigueta Jordana, Miguel Ángel; Oñate Ibáñez de Navarra, Eugenio (Springer, 2020-01)
    Article
    Restricted access - publisher's policy
    Changes in direction and cross section in supercritical hydraulic channels generate shockwaves which result in an increase in flow depth with regard to that for uniform regime. These disturbances are propagated downstream ...

  • Analysis of fluid soil-structure interaction problems with the particle finite element method (PFEM) 

    Oñate Ibáñez de Navarra, Eugenio; Celigueta Jordana, Miguel Ángel; Idelsohn Barg, Sergio Rodolfo; Salazar González, Fernando; Larese De Tetto, Antonia; Rossi, Riccardo; Suárez Arroyo, Benjamín; Morán, R. (2012)
    External research report
    Open Access
    We present some developments in the Particle Finite Element Method (PFEM) for analysis of coupled problems in mechanics involving fluid-soil-structure interaction (FSSI). The PFEM uses an updated Lagrangian description to ...

  • Possibilities of the particle finite element method in computational mechanics 

    Oñate Ibáñez de Navarra, Eugenio; Idelsohn Barg, Sergio Rodolfo; Celigueta Jordana, Miguel Ángel; Rossi, Riccardo; Latorre, Salvador (2010)
    External research report
    Open Access
    We present some developments in the formulation of the Particle Finite Element Method (PFEM) for analysis of complex coupled problems in fluid and solid mechanics accounting for fluid-structure interaction and coupled ...

  • Shear transfer behavior in composite slabs under 4-point standard and uniform-load tests 

    Soltanalipour, Milad; Ferrer Ballester, Miquel; Marimón Carvajal, Federico; Holomek, Josef; Bajer, Miroslav; Melcher, Jindrich; Karmazínová, Marcela (2020-01)
    Article
    Restricted access - author's decision
    The 4-point bending test, prescribed by most standards, is the conventional test used to determine the shear resistance of steel-concrete composite slabs, whereas loading requirements are commonly specified in terms of ...

  • PFEM–DEM for particle-laden flows with free surface 

    Franci, Alessandro; Pouplana Sarda, Ignasi de; Casas González, Guillermo; Celigueta Jordana, Miguel Ángel; González Usúa, Joaquín; Oñate Ibáñez de Navarra, Eugenio (Springer, 2020-01)
    Article
    Open Access
    This work proposes a fully Lagrangian formulation for the numerical modeling of free-surface particle-laden flows. The fluid phase is solved using the particle finite element method (PFEM), while the solid particles embedded ...

  • Lagrangian analysis of multiscale particulate flows with the particle finite element method 

    Oñate Ibáñez de Navarra, Eugenio; Celigueta Jordana, Miguel Ángel; Latorre Sánchez, Juan Salvador; Casas González, Guillermo; Rossi, Riccardo; Rojek, Jerzy (Springer, 2014-05)
    Article
    Open Access
    We present a Lagrangian numerical technique for the analysis of flows incorporating physical particles of different sizes. The numerical approach is based on the particle finite element method (PFEM) which blends concepts ...
