  • Red Aulas CIMNE: espacios de colaboración en temas docentes y de I+D en distintas universidades, empresas y centros de investigación de diversos países 

    Oñate Ibáñez de Navarra, Eugenio; Guzmán, Francisco; Bugeda Castelltort, Gabriel; Corestein Poupeau, Georgina; Zárate Araiza, José Francisco (Escola Universitària d'Enginyeria Tècnica Industrial de Barcelona (EUETIB), 2004)
    Text en actes de congrés
    Accés obert
    La mayoría de los avances de I+D que hoy en día se producen quedan limitados en función de necesidades locales. La causa principal es la falta de medios para proyectar la I+D hacia entornos donde pueda ser exitosamente ...
  • Análisis elastodinámico de sólidos mediante el método sin malla de puntos finitos 

    Perazzo Maggi, Franco Orlando; Miquel Canet, Juan; Oñate Ibáñez de Navarra, Eugenio (2002)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    El trabajo presenta los principales aspectos de la implementación del método numérico sin malla de Puntos Finitos (MPF) para la solución de problemas en la dinámica lineal de sólidos. Para resolver numéricamente el sistema ...
  • Global search methods for nonlinear optimisation: a new probabilistic-stochastic approach 

    Bugeda Castelltort, Gabriel; Balsa-Canto, E; Thamotheram, C; Oñate Ibáñez de Navarra, Eugenio; Zárate Araiza, José Francisco (International Centre for Numerical Methods in Engineering (CIMNE), 2003)
    Text en actes de congrés
    Accés obert
    In this work the problem of overcoming local minima in the solution of nonlinear optimisation problems is addressed. As a first step, the existing nonlinear local and global optimisation methods are reviewed so as to ...
  • 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 ...
