    Accés obert
    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)
    Text en actes de congrés
    Accés obert
    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 ...
  • Neural networks for optimal control of aircraft landing systems 

    Lau, K; López González, Roberto; Oñate Ibáñez de Navarra, Eugenio (International Association of Engineers (IAENG), 2007)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In this work we present a variational formulation for a multilayer perceptron neural network. With this formulation any learning task for the neural network is defined in terms of finding a function that is an extremal ...
  • Pressure measurement in 2D sloshing simulations with SPH
