  • Reshaping of large aeronautical structural parts: a simplified simulation approach 

    Mena Andrade, Ramiro; Aguado, José Vicente; Guinard, S.; Huerta, Antonio (American Institute of Physics (AIP), 2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Large aeronautical structural parts present important distortions after machining. This problem is caused by the presence of residual stresses, which are developed during previous manufacturing steps (quenching). Before ...
  • ComplexityCosts D2.2 - Model Implementation 

    Cristóbal, Samuel; Delgado, Luis; Tanner, Graham; Cook, Andrew; Pérez, David; Villardi de Montlaur, Adeline de (2015-08-28)
    Report de recerca
    Accés obert
    The primary objective of ComplexityCosts is to better understand ATM network performance trade-offs for different stakeholder investment mechanisms under certain disruptions. In this report, software implementation of the ...
  • Engagement of civil engineer students in the first academic year 

    Estela Carbonell, M. Rosa; Díez, Pedro (International Centre for Numerical Methods in Engineering (CIMNE), 2018)
    Text en actes de congrés
    Accés obert
    Stronger student engagement or improved student engagement are common instructional objectives expressed by Higher Educational Institutions. They aim, in particular, at reducing the early dropouts of Science, technology, ...
  • Algebraic PGD for tensor separation and compression: an algorithmic approach 

    Díez, Pedro; Zlotnik, Sergio; García González, Alberto; Huerta, Antonio (2018-07)
    Article
    Accés obert
    Proper Generalized Decomposition (PGD) is devised as a computational method to solve high-dimensional boundary value problems (where many dimensions are associated with the space of parameters defining the problem). The ...
  • A superconvergent hybridisable discontinuous Galerkin method for linear elasticity 

    Sevilla, Rubén; Giacomini, Matteo; Karkoulias, Alexandros; Huerta, Antonio (John Wiley & sons, 2018-10-12)
    Article
    Accés restringit per política de l'editorial
    The first superconvergent hybridisable discontinuous Galerkin method for linear elastic problems capable of using the same degree of approximation for both the primal and mixed variables is presented. The key feature of ...
  • Opposite subduction polarity in adjacent plate segments 

    Peral, Mireia; Kiraly, Agnes; Zlotnik, Sergio; Funiciello, Francesca; Fernandez Ortiga, Manel; faccenna, claudio; Vergés, Jaume (2018-09)
    Article
    Accés restringit per política de l'editorial
    Active and fossil subduction systems consisting of two adjacent plates with opposite retreating directions occur in several areas on Earth, as the Mediterranean or Western Pacific. The goal of this work is to better ...
  • An optimization-based phase-field method for continuous-discontinuous crack propagation 

    Geelen, Rudy J.; Liu, Yingjie; Dolbow, John E.; Rodríguez Ferran, Antonio (John Wiley & sons, 2018-10-05)
    Article
    Accés restringit per política de l'editorial
    A new continuous-discontinuous strategy for the computational modeling of crack propagation within the context of phase-field models of fracture is presented. The method is designed to introduce and update a sharp crack ...
  • Alternative Trajectory Options for Delay Reduction in Demand and Capacity Balancing 

    Xu, Yan; Dalmau Codina, Ramon; Melgosa Farrés, Marc; Villardi de Montlaur, Adeline de; Prats Menéndez, Xavier (2018)
    Text en actes de congrés
    Accés obert
    Aiming to a more collaborative demand and capacity balancing (DCB), in the scope of trajectory based operations, this paper presents an approach that takes alternative trajectories into a DCB optimization algorithm. ...
  • Eigenvalue and eigenmode synthesis in elastically coupled subsystems 

    Magrans Fontrodona, Francesc Xavier; Poblet-Puig, Jordi (2018-10-13)
    Article
    Accés restringit per política de l'editorial
    A method to synthesize the modal characteristics of a system from the modal characteristics of its subsystems is proposed. The interest is focused on those systems with elastic links between the parts which is the main ...
  • A simple microstructural viscoelastic model for flowing foams 

    Ibáñez, Rubén; Scheuer, Adrien; Abisset-Chavanne, Emmanuelle; Chinesta, Francisco; Huerta, Antonio; Keunings, Roland (2018-04-28)
    Article
    Accés restringit per política de l'editorial
    The numerical modelling of forming processes involving the flow of foams requires taking into account the different problem scales. Thus, in industrial applications a macroscopic approach is suitable, whereas the macroscopic ...
  • A face-centred finite volume method for second-order elliptic problems 

    Sevilla, Rubén; Giacomini, Matteo; Huerta, Antonio (John Wiley & sons, 2018-08-24)
    Article
    Accés restringit per política de l'editorial
    This work proposes a novel finite volume paradigm, the face-centred finite volume (FCFV) method. Contrary to the popular vertex (VCFV) and cell (CCFV) centred finite volume methods, the novel FCFV defines the solution on ...
  • Experimental and numerical study of Advanced Transfer Path Analysis applied to a box prototype 

    Aragonès Martín, Àngels; Poblet-Puig, Jordi; Arcas, Kevin; Vicens Rodríguez, Pere; Magrans Fontrodona, Francesc Xavier; Rodríguez Ferran, Antonio (2019-01-01)
    Article
    Accés restringit per política de l'editorial
    Advanced Transfer Path Analysis (ATPA) is a technique that allows the characterisation of vibroacoustic systems not only from the point of view of contributions but also topologically by means of the path concept. Some of ...
