  • CBS stabilization in dynamics of solids using explicit time integration 

    Rojek, Jerzy; Oñate Ibáñez de Navarra, Eugenio; Taylor, R L (2004)
    Conference report
    Open Access
    The characteristic based split (CBS) stabilization procedure developed originally in fluid mechanics has been adapted successfully to solid mechanics problems. The CBS algorithm has been implemented within a finite element ...
  • Contact analysis in the discrete element method : modelling and computational aspects 

    Rojek, Jerzy; Labra, C.; Oñate Ibáñez de Navarra, Eugenio (2011)
    Conference report
    Restricted access - publisher's policy
    In the discrete element method (DEM) material is modelled as a collection of rigid particles of different shape interacting one with another with contact forces. The formulation presented in this work employs spherical ...
  • Coupling of FEFLO with SIMPACT 

    Arteaga Gómez, J.; Löhner, R; Rojek, Jerzy; Oñate Ibáñez de Navarra, Eugenio (American Institute of Aeronautics and Astronautics (AIAA), 2006)
    Conference report
    Open Access
    The ability to predict accurately fluid-structure interaction problems is of fundamental importance for design, analysis and reconstruction in many areas of mechanical and civil engineering. In order to characterize the ...

    Labra, C.; Rojek, Jerzy; Oñate Ibáñez de Navarra, Eugenio (2017-03)
    Article
    Open Access
    This paper presents advanced computer simulation of rock cutting process typical for excavation works in civil engineering. Theoretical formulation of the hybrid discrete/finite element model has been presented. The discrete ...

  • 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)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • 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 ...
  • Modelling and simulation of the effect of blast loading on structures using an adaptive blending of discrete and finite element methods 

    Labra, C.; Oñate Ibáñez de Navarra, Eugenio; Zárate Araiza, José Francisco; Rojek, Jerzy (2011)
    Conference report
    Open Access
    We present a new computational model for predicting the effect of blast loading on structures. The model is based in the adaptive coupling of the finite element method (FEM) and the discrete element method (DEM) for the ...
  • Multiscale analysis using a coupled discrete/finite element model 

    Rojek, Jerzy; Oñate Ibáñez de Navarra, Eugenio (Techno press, 2008-03)
    Article
    Restricted access - publisher's policy
    The present paper presents multiscale modelling via coupling of the discrete and finite element methods. Theoretical formulation of the discrete element method using spherical or cylindrical particles has been briefly ...
  • Non linear dynamic analysis of solids using linear triangles and tetrahedra 

    Oñate Ibáñez de Navarra, Eugenio; Rojek, Jerzy; Taylor, R L; Zienkiewicz, Olgierd Cecil (2003)
    Conference report
    Open Access
    The basis of the FIC method is the satisfaction of the standard equations for balance of momentum (equilibrium of forces) and mass conservation in a domain of finite size and retaining higher order terms in the Taylor ...
