  • Mechanical oscillations in biological tissues as a result of delayed rest-length changes 

    Muñoz Romero, José; Dingle, Monica; Wenzel, Manuel (American Institute of Physics (AIP), 2018-11-26)
    Article
    Accés obert
    Oscillatory behavior in tissue biology is ubiquitous and may be observed in the form of either chemical or mechanical signals. We present here and solve a mechanical cell model that exhibits oscillations emerging from ...
  • Active superelasticity in three-dimensional epithelia of controlled shape 

    Latorre Ibars, Ernest; Kale, Sohan Sudhir; Casares, Laura; Arroyo Balaguer, Marino (Macmillan Publishers, 2018-11)
    Article
    Accés restringit per política de l'editorial
    Fundamental biological processes are carried out by curved epithelial sheets that enclose a pressurized lumen. How these sheets develop and withstand three-dimensional deformations has remained unclear. Here we combine ...
  • Numerical estimation of the bearing capacity of resistance spot welds in martensitic boron steels using a J-integral fracture criterion 

    Dorribo Dorribo, Daniel; Greve, Lars; Díez, Pedro; Arias Vicente, Irene; Larráyoz Izcara, Xabier (2018-08-01)
    Article
    Accés restringit per política de l'editorial
    Predicting the bearing capacity of resistance spot welds (RSW) during vehicle crash tests has become a crucial task for the automotive industry, since the recent introduction of advanced high strength steels (AHSS) such ...
  • Cell-DEVS modeling and simulation of artificial hydraulic fracturing of rocks in boreholes (WIP) 

    Oyelowo, I.; Wainer, G.; Echegini, N.S.; Ukeme, J.B.; Zlotnik, Sergio (Society for Computer Simulation International, 2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Hydraulic Fracturing is a technique used in the extraction and exploration of oil and gas. During hydraulic fracturing, a high-pressure fluid is injected into a wellbore; this fluid flows through some artificially made ...
  • Piezoelectric mimicry of flexoelectricity 

    Abdollahi Hosnijeh, Amir; Vazquez Sancho, Fabian; Catalan, Gustau (American Institute of Physics (AIP), 2018-11-15)
    Article
    Accés obert
    The origin of “giant” flexoelectricity, orders of magnitude larger than theoretically predicted, yet frequently observed, is under intense scrutiny. There is mounting evidence correlating giant flexoelectriclike effects ...
  • An upwind cell centred Total Lagrangian finite volume algorithm for nearly incompressible explicit fast solid dynamic applications 

    Haider, Jibran; Lee, Chun Hean; Gil, Antonio; Huerta, Antonio; Bonet, Javier (2018-10-01)
    Article
    Accés restringit per política de l'editorial
    The paper presents a new computational framework for the numerical simulation of fast large strain solid dynamics, with particular emphasis on the treatment of near incompressibility. A complete set of first order hyperbolic ...
  • A locking-free face-centred finite volume (FCFV) method for linear elastostatics 

    Sevilla, Rubén; Giacomini, Matteo; Huerta, Antonio (2019-02-01)
    Article
    Accés restringit per política de l'editorial
    A face-centred finite volume (FCFV) method is proposed for linear elastostatic problems. The FCFV is a mixed hybrid formulation, featuring a system of first-order equations, that defines the unknowns on the faces (edges ...
  • A superconvergent HDG method for stokes flow with strongly enforced symmetry of the stress tensor 

    Giacomini, Matteo; Karkoulias, Alexandros; Sevilla, Rubén; Huerta, Antonio (2018-12)
    Article
    Accés restringit per política de l'editorial
    This work proposes a superconvergent hybridizable discontinuous Galerkin (HDG) method for the approximation of the Cauchy formulation of the Stokes equation using same degree of polynomials for the primal and mixed variables. ...
  • Sampling-based stochastic analysis of the PKN model for hydraulic fracturing 

    Garikapati, Hasini; V. Verhoosel, Clemens; van Brummelen, Harald; Zlotnik, Sergio; Díez, Pedro (2018-10-02)
    Article
    Accés obert
    Hydraulic fracturing processes are surrounded by uncertainty, as available data is typically scant. In this work, we present a sampling-based stochastic analysis of the hydraulic fracturing process by considering various ...
  • 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, ...
