  • Una formulación general para el análisis elastoplástico de estructuras sometidas a grandes movimientos 

    Oliver Olivella, Xavier; Oñate Ibáñez de Navarra, Eugenio (1982)
    Conference report
    Open Access
    Se presenta una formulación para el estudio de es­tructuras tipo lámina, placa, arco o viga sometidos a grandes movimientos en régimen elastoplástico. La formulación utiliza la descripción Lagrangiana de la deformación y ...

  • Una formulación de bandas finitas para el análisis de placas, puentes y láminas de revolución 

    Casteleiro Maldonado, Manuel; Suárez Arroyo, Benjamín; Oñate Ibáñez de Navarra, Eugenio (1982)
    Conference report
    Open Access
    En el presente artículo se desarrolla una técnica para disipar tensiones de tracción en materiales que no admiten dichas tensiones, y que se aplica al análisis elástico lineal -de una presa bóveda proyectada en la cuenca ...

  • Comportamiento sísmico de los monumentos históricos 

    Barbat Barbat, Horia Alejandro (AIBIS, 2001)
    Conference report
    Open Access
    En el artículo se estudia el comportamiento sísmico de las estructuras históricas utilizando el concepto de vulnerabilidad sísmica desde un punto de vista puramente intuitivo. Se considera que las construcciones antiguas, ...

    Chiroiu, L; Goula Suriñach, Xavier; Roca Adrover, Antoni; Susagna Vidal, Teresa; Barbat Barbat, Horia Alejandro; Pujades Beneit, Lluís (AIBIS, 2005)
    Conference report
    Open Access
    El método del espectro de capacidad constituye una herramienta nueva que se puede utilizar para el análisis de daños estructurales y no estructurales debidos a una acción sísmica tanto para la generación de escenarios de ...

  • Las herramientas SIG en el análisis de vulnerabilidad y escenarios de riesgo sísmico 

    Lantada, Nieves; Pujades Beneit, Lluís; Barbat Barbat, Horia Alejandro (UNEX, 2003)
    Conference report
    Open Access
    An integrated GIS-based analysis (using ArcView GIS) is performed in order to estimate risk scenarios for EMS-98 seismic intensities in Barcelona (Spain), according to a methodology developed within the Risk-UE Project of ...

  • A sensibility analysis to geometric and cutting conditions using the particle finite element method (PFEM) 

    Rodriguez Prieto, Juan Manuel; Arrazola, Pedro; Cante Terán, Juan Carlos; Kortabarria, Arratibel; Oliver Olivella, Xavier (Red Hook, 2013)
    Conference report
    Open Access
    The (PFEM) is employed to simulate orthogonal metal cutting of 42CD4 steel. The objectives of this work are mainly three: The first one is to validate PFEM strategies as an efficient tool for numerical simulation of metal ...

  • Multi-objective design optimisation of stamping process for advanced high strength steels 

    Lee, Dong Seop; Pons Prats, Jordi; Espinoza Román, Héctor Gabriel; Fruitós Bickham, Óscar Alejandro; Oñate Ibáñez de Navarra, Eugenio (2012)
    Conference report
    Restricted access - publisher's policy
    The paper investigates the multi-objective design optimisation of stamping process to control both the shape and quality of final Advanced High Strength Steels (AHSSs) in terms of springback and safety using Distributed ...

  • Robust active shock control bump design optimisation using parallel hybrid-MOGA 

    Lee, Dong Seop; Bugeda Castelltort, Gabriel; Periaux, Jacques Francis; Oñate Ibáñez de Navarra, Eugenio (2011)
    Conference report
    Open Access
    The paper investigates a robust optimisation for detail design of active shock control bump on a transonic Natural Laminar Flow (NLF) aerofoil using a Multi-Objective Evolutionary Algorithm (MOEA) coupled to Computational ...

  • Parallel adaptive mesh refinement for incompressible flow problems 

    Cotela Dalmau, Jordi; Rossi, Riccardo; Oñate Ibáñez de Navarra, Eugenio; Lafontaine, Nelson Maireni; Idelsohn Barg, Sergio Rodolfo (2011)
    Conference report
    Open Access
    We present an algorithm for the solution of the incompressible Navier- Stokes equations combined with local refinement of the mesh based on an error estimation. Our solution strategy is based on well-established CFD ...

  • 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)
    Conference report
    Restricted access - publisher's policy
    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 ...

  • 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 ...

  • Modeling of surface wear by the particle finite element method: application to tunneling processes 

    Carbonell Puigbó, Josep Maria; Suárez Arroyo, Benjamín; Oñate Ibáñez de Navarra, Eugenio (2009)
    Conference report
    Open Access
    This work introduces the advances in the Particle Finite Element Method (PFEM) for the modeling of contact and wear between solid materials. The PFEM is an original conjunction of solution strategies. The method has its ...
