  • Hybridizable discontinuous Galerkin p-adaptivity for wave problems 

    Giorgiani, Giorgio; Fernandez Mendez, Sonia; Huerta, Antonio (2012)
    Conference report
    Open Access
    A p-adaptive Hybridizable Discontinuous Galerkin (HDG) method is presented for the solution of wave problems. The HDG method allows to drastically reduce the coupled degrees of freedom of the computation seeking for an ...

    A recent line of research concerns the integration of ant colony optimization and constraint programming. Hereby, constraint programming is used for eliminating parts of the search tree during the solution construction of ...
  • Hydration kinetics of compacted low-density bentonite 

    Dieudonné, A.C.; Charlier, R.; Romero Morales, Enrique Edgar (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    The hydration kinetics of a compacted low-density bentonite is investigated from both experimental and numerical points of view. A water retention curve and water permeability under saturated conditions were determined to ...
  • Hydraulic behaviour of a representative structural volume for containment buildings 

    Jason, L; Pijaudier-Cabot, Gilles; Ghavamian, S; Huerta, Antonio (2007-07)
    Article

    Brittle materials propagate opening cracks under tension. When stress increases beyond a critical magnitude, then quasistatic crack propagation becomes unstable. In the presence of several precracks, a brittle material ...
  • Hydraulic fracture during epithelial stretching 

    Casares, Laura; Vincent, Romaric; Zalvidea, Dobryna; Campillo, Noelia; Navajas, Daniel; Arroyo Balaguer, Marino; Trepat Guixer, Xavier (2015-03-01)
    Article
    Open Access
    The origin of fracture in epithelial cell sheets subject to stretch is commonly attributed to excess tension in the cells' cytoskeleton, in the plasma membrane, or in cell-cell contacts. Here, we demonstrate that for a ...
