    Medellín is the second largest city of Colombia with more than 2 million inhabitants according to the latest census and with more than 240,000 public and private buildings. It is located on an intermediate seismic hazard ...
  • New tension-compression damage model for complex analysis of concrete structures 

    Paredes, Jairo A.; Oller Martínez, Sergio Horacio; Barbat Barbat, Horia Alejandro (American Society of Civil Engineers (ASCE), 2016-10)
    Article
    Accés obert
    A new damage model, based on continuum damage mechanics and simulating the opening, closing, and reopening of cracks in concrete using only one surface of discontinuity, is proposed in this article. The model complies with ...
  • The domain interface method in non-conforming domain decomposition multifield problemsdomain decomposition multifield problems 

    Lloberas Valls, Oriol; Cafiero, Mailhyn E.; Cante Terán, Juan Carlos; Ferrer Ferré, Àlex; Oliver Olivella, Xavier (2016-12)
    Article
    Accés obert
    The Domain Interface Method (DIM) is extended in this contribution for the case of mixed fields as encountered in multiphysics problems. The essence of the non-conforming domain decomposition technique consists in a ...
  • Finite element modelling of internal and multiple localized cracks 

    Saloustros, Savvas; Pelà, Luca; Cervera Ruiz, Miguel; Roca Fabregat, Pedro (2017-02)
    Article
    Accés restringit per política de l'editorial
    Tracking algorithms constitute an efficient numerical technique for modelling fracture in quasi-brittle materials. They succeed in representing localized cracks in the numerical model without mesh-induced directional bias. ...
  • Multiscale thermo-mechanical analysis of multi-layered coatings in solar thermal applications 

    Montero-Chacón, Francisco; Zaghi, Stefano; Rossi, Riccardo; García-Pérez, Elena; Heras Pérez, Irene; Martínez García, Javier; Oller Martínez, Sergio Horacio; Doblaré, Manuel (2017-05)
    Article
    Accés restringit per política de l'editorial
    Solar selective coatings can be multi-layered materials that optimize the solar absorption while reducing thermal radiation losses, granting the material long-term stability. These layers are deposited on structural materials ...
  • An updated probabilistic seismic hazard assessment for Romania and comparison with the approach and outcomes of the SHARE Project 

    Pavel, Florin; Vacareanu, Radu; Douglas, John; Radulian, Micrea; Cioflan, Carmen; Barbat Barbat, Horia Alejandro (2016-06-01)
    Article
    Accés restringit per política de l'editorial
    The probabilistic seismic hazard analysis for Romania is revisited within the framework of the BIGSEES national research project (http://infp.infp.ro/bigsees/default.htm) financed by the Romanian Ministry of Education and ...
  • A FIC-based stabilized finite element formulation for turbulent flows 

    Cotela Dalmau, Jordi; Rossi, Riccardo; Oñate Ibáñez de Navarra, Eugenio (2016-11-21)
    Article
    Accés obert
    We present a new stabilized finite element (FEM) formulation for incompressible flows based on the Finite Increment Calculus (FIC) framework. In comparison to existing FIC approaches for fluids, this formulation involves ...
  • Turbulent separated shear flow control by surface plasma actuator: experimental optimization by genetic algorithm approach 

    Benard, N.; Pons Prats, Jordi; Periaux, Jacques Francis; Bugeda Castelltort, Gabriel; Braud, P.; Bonnet, J.P.; Moreau, E. (2016-02)
    Article
    Accés restringit per política de l'editorial
    The potential benefits of active flow control are no more debated. Among many others applications, flow control provides an effective mean for manipulating turbulent separated flows. Here, a nonthermal surface plasma ...
  • Velocity-based formulations for standard and quasi-incompressible hypoelastic-plastic solids 

    Franci, Alessandro; Oñate Ibáñez de Navarra, Eugenio; Carbonell Puigbó, Josep Maria (John Wiley & Sons, 2016-09)
    Article
    Accés restringit per política de l'editorial
    We present three velocity-based updated Lagrangian formulations for standard and quasi-incompressible hypoelastic-plastic solids. Three low-order finite elements are derived and tested for non-linear solid mechanics problems. ...
  • A hierarchical finite element for composite laminated beams using a refined zigzag theory 

    Nallim, Liz G.; Oller Martínez, Sergio Horacio; Oñate Ibáñez de Navarra, Eugenio; Flores, Fernando Gabriel (2017-03)
    Article
    Accés restringit per política de l'editorial
    In this work a kinematics for laminated beams enriched with a refined formulation ZigZag (RZT), originally presented by Tessler et al. in 2007, introduced in a hierarchical one dimensional type “p” finite element is ...
