    The aim of the present study is to propose a reliable engineering procedure to analyze bridges subjected to wind loads by-passing the expensive wind tunnel tests thanks to numerical simulations. These exploit Kratos, a ...
  • Dimensional hyper-reduction of nonlinear finite element models via empirical cubature 

    Hernández Ortega, Joaquín Alberto; Caicedo Silva, Manuel Alejandro; Ferrer Ferré, Àlex (2017-01)
    Article
    Accés obert
    We present a general framework for the dimensional reduction, in terms of number of degrees of freedom as well as number of integration points (“hyper-reduction”), of nonlinear parameterized finite element (FE) models. The ...

    Nowadays, the model order reduction techniques have become an intensive research eld because of the increasing interest in the computational modeling of complex phenomena in multi-physic problems, and its conse- quent ...
  • The Double Hierarchy Method: a parallel 3D contact method for the interaction of spherical particles with rigid FE boundaries using the DEM 

    Santasusana, Miquel; Irazábal González, Joaquín; Oñate Ibáñez de Navarra, Eugenio; Carbonell Puigbó, Josep Maria (Springer, 2016-07)
    Article
    Accés restringit per política de l'editorial
    In this work, we present a new methodology for the treatment of the contact interaction between rigid boundaries and spherical discrete elements (DE). Rigid body parts are present in most of large-scale simulations. The ...
  • Cohesive surface model for fracture based on a two-scale formulation: computational implementation aspects 

    Toro, Sebastian; Sánchez, P.J.; Podestá, J.M.; Blanco, P.J.; Huespe, Alfredo Edmundo; Feijóo, R.A. (2016-10)
    Article
    Accés obert
    The paper describes the computational aspects and numerical implementation of a two-scale cohesive surface methodology developed for analyzing fracture in heterogeneous materials with complex micro-structures. This approach ...
  • Numerical validation of the incremental launching method of a steel bridge through a small-scale experimental study 

    Chacón Flores, Rolando Antonio; Uribe Sasiain, Nicolás; Oller Martínez, Sergio Horacio (2016-02)
    Article
    Accés restringit per política de l'editorial
    This article presents an experimental and a numerical study of an incremental launching process of a steel bridge. The former is deployed in a scale-reduced laboratory,whereas the latter is performed using the finite ...
  • High-fidelity prediction of crack formation in 2D and 3D pullout tests 

    Benedetti, Lorenzo; Cervera Ruiz, Miguel; Chiumenti, Michèle (2016-08)
    Article
    Accés restringit per política de l'editorial
    This paper presents the 2D and 3D numerical analysis of pullout tests on steel anchorages in concrete blocks using standard and mixed finite elements. A novel (stabilized) mixed formulation in the variables of total strain ...
  • A laminated structural finite element for the behavior of large non-linear reinforced concrete structures 

    Escudero Torres, Cuauhtemoc; Oller Martínez, Sergio Horacio; Martínez García, Javier; Barbat Barbat, Horia Alejandro (2016-10)
    Article
    Accés restringit per política de l'editorial
    In order to correctly predict the kinematics of complex structures, analysis using three-dimensional finite elements (3DFEs) seems to be the best alternative. However, simulation of large multi-layered structures with many ...
