  • Comparison of high-order continuous and hybridizable discontinuous {G}alerkin methods in incompressible fluid flow problems 

    Paipuri, Mahendra; Fernández Méndez, Sonia; Tiago, Carlos (2018-10-01)
    Article
    Open Access
    The computational efficiency and the stability of Continuous Galerkin (CG) methods, with Taylor–Hood approximations, and Hybridizable Discontinuous Galerkin (HDG) methods are compared for the solution of the incompressible ...
  • Smart helical structures inspired by the pellicle of euglenids 

    Noselli, Giovanni; Arroyo Balaguer, Marino; DeSimone, Antonio (2019-02)
    Article
    Restricted access - publisher's policy
    This paper deals with a concept for a reconfigurable structure bio-inspired by the cell wall architecture of euglenids, a family of unicellular protists, and based on the relative sliding of adjacent strips. Uniform sliding ...
  • Fully coupled numerical model of actin treadmilling in the lamellipodium of the cell 

    Kollepara, Kiran Sagar; Mulye, Paris D.; Sáez Viñas, Pablo (John Wiley & sons, 2018-12)
    Article
    Restricted access - publisher's policy
    Cells rely on an interplay of subcellular elements for motility and migration. Certain regions of motile cells, such as the lamellipodium, are made of a complex mixture of actin monomers and filaments, which polymerize at ...
  • A multidimensional data-driven sparse identification technique: the sparse proper generalized decomposition 

    Ibáñez Pinillo, Rubén; Abisset Chavanne, Emmanuelle; Ammar, Amine; González Ibáñez, David; Cueto Prendes, Elias; Huerta, Antonio; Duval, Jean Louis; Chinesta Soria, Francisco (2018-01-01)
    Article
    Open Access
    Sparse model identification by means of data is especially cumbersome if the sought dynamics live in a high dimensional space. This usually involves the need for large amount of data, unfeasible in such a high dimensional ...
  • 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
    Open Access
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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 ...
  • Piezoelectric mimicry of flexoelectricity 

    Abdollahi Hosnijeh, Amir; Vazquez Sancho, Fabian; Catalan, Gustau (American Institute of Physics (AIP), 2018-11-15)
    Article
    Open Access
    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 Carbonell, Javier (2018-10-01)
    Article
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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 (2019-02)
    Article
    Open Access
    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 ...
