  • A set of algorithms to correct a geometry in order to be meshed 

    Ribo Rodriguez, Ramon; Bugeda Castelltort, Gabriel; Oñate Ibáñez de Navarra, Eugenio (2000)
    Text en actes de congrés
    Accés obert
    One of the major difficulties in meshing 3D complex geometries is to deal with non proper geometrical definitions coming from CAD systems. Typically, CAD systems don’t take care of the proper definition of the geometries ...
  • A numerical approach to simulate the behavior of fiber reinforced composite materials 

    Car, Eduardo J.; Oller Martínez, Sergio Horacio; Oñate Ibáñez de Navarra, Eugenio (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2000)

  • Parameter identification of large-scale magnetorheological dampers in a benchmark building 

    Bahar, Arash; Pozo Montero, Francesc; Acho Zuppa, Leonardo; Rodellar Benedé, José; Barbat Barbat, Horia Alejandro (2009)
    Text en actes de congrés
    Accés obert
    Magnetorheological (MR) dampers are devices that can be use d for vibration re- duction in structures. However, to use these devices in an ef fective way, a precise modeling is required. In this sense, in this paper we ...
  • A simulation tool for parachute/payload systems 

    Flores Le Roux, Roberto Maurice; Ortega, Enrique; Vallés Fluvià, J.; Oñate Ibáñez de Navarra, Eugenio (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
    Text en actes de congrés

    The design and evaluation of parachute-payload systems is a technology field in which numerical analysis tools can make very important contributions. This work describes a new development from CIMNE in this area, a coupled ...
  • Stochastic and Robust design procedures applied to the optimization with uncertainties 

    Pons Prats, Jordi; Bugeda Castelltort, Gabriel; Zárate Araiza, José Francisco; Oñate Ibáñez de Navarra, Eugenio (2011)
    Text en actes de congrés
    Accés obert
    Engineers agree with the fact that uncertainty is an important issue to get a better model of real behavior. Uncertainty quantification techniques have been largely developed during the recent years; Stochastic and ...
  • The Particle Finite Element Method (PFEM): an effective numerical technique for solving coastal engineering problems 

    Oñate Ibáñez de Navarra, Eugenio; Celigueta Jordana, Miguel Ángel; Idelsohn Barg, Sergio Rodolfo (2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We present some developments in the Particle Finite Element Method (PFEM) for the solution of complex coupled problems in coastal engineering involving fluid-soil-structure interaction (FSSI) such as the stability of ...
  • Advances in the Discrete Element Method for drilling mechanics problems 

    Oñate Ibáñez de Navarra, Eugenio; Arrufat Garcia, Ferran; Zárate Araiza, José Francisco; Ubach Fuentes, Pere-Andreu; Gandikota, Varadaraju; Ring, Lev (2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We present recent developments in the Discrete Element method (DEM) for analysis of drilling mechanics problems typical in the oil and gas industry. A new local DEM constitutive model able to predict the non-linear behavior ...
  • Multi-objective design optimisation of a 3D-rail stamping process using a robust multi-objective optimisation platform (RMOP) 

    Lee, DongSeop; Coma Company, Martí; Espinoza Román, Héctor Gabriel; Fruitós Bickham, Óscar Alejandro; Pons Prats, Jordi (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2013)
    Text en actes de congrés
    Accés obert
    The paper investigates the multi-objective design optimisation of a stamping process to control the final shape and the final quality using advanced high strength steels. The design problem of the stamping process is ...
  • Finite element computation of diphthong sounds using tuned two-dimensional vocal tracts 

    Arnela, Marc; Guasch Fortuny, Oriol; Codina, Ramon; Espinoza Román, Héctor Gabriel (European Acoustics Association (EEA), 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Finite element methods (FEM) are increasingly being used to simulate the acoustics of the vocal tract. For vowel production, the irreducible wave equation for the acoustic pressure is typically solved. However, diphthong ...
  • Comparing a sumulated loss scenario with the observed earthquake damage: the Lorca 2011 case study 

    Salgado Galvez, Mario A.; Carreño Tibaduiza, Martha Liliana; Barbat Barbat, Horia Alejandro; Cardona Arboleda, Omar Dario (2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A loss assessment was performed for the buildings of Lorca, Spain, considering an earthquake hazard scenario with similar characteristics to those of a real event which occurred on May 11th 2011, in terms of epicentre, ...
