  • Heat transport with advection in fractured rock 

    Pérez Carreras, Adrià; Carol, Ignacio; Prat Catalán, Pere (2019)
    Conference report
    Open Access
    In the transport of heat in porous media, diffusion generally dominates over advection due to slow fluid velocities imposed by low permeability. This is the reason why standard Galerkin formulation leading to extra ...
  • Soil surface boundary condition in desiccating soils 

    Cuadrado Cabello, Agustín; Encalada Lopez, David Alejandro; Ledesma Villalba, Alberto; Prat Catalán, Pere (The Icelandic Geotechnical Society (IGS), 2019)
    Conference report

    Soils undergoing desiccation exhibit shrinkage and eventually cracking. That may become an environmental problem in practical applications. From a Geotechnical perspective, it is possible to solve the corresponding ...
  • A stabilized finite element method for incompressible viscous flows using a finite increment calculus formulation 

    Oñate Ibáñez de Navarra, Eugenio (1999-02)
    External research report
    Open Access
    A stabilized finite element formulation for incompressible viscous flows is derived. The starting point are the modified Navier-Stokes equations incorporating naturally the necessary stabilization terms via a finite increment ...
  • Rotation-free triangular plate and shell elements 

    Oñate Ibáñez de Navarra, Eugenio; Zárate Araiza, José Francisco (1999-03)
    External research report
    Open Access
    The paper describes how the finite element method and the finite volume method can be successfully combined to derive two new families of thin plate and shell triangles with translational degrees of freedom as the only ...
  • Load aggressiveness on different pavement structures due to the weight increase of heavy vehicles from 40 tonnes to 44 tonnes 

    Martínez Reguero, Adriana Haydée; Campos Cacheda, Jose Magin (2019-09)
    Article
    Open Access
    The load capacity of goods vehicles is a critical variable in calculating transport costs. In Europe, the Council Directive 96/53/EC establishes the maximum weight and dimensions of goods vehicles in international traffic ...
  • PFEM–DEM for particle-laden flows with free surface 

    Franci, Alessandro; Pouplana Sarda, Ignasi de; Casas González, Guillermo; Celigueta Jordana, Miguel Ángel; González Usúa, Joaquín; Oñate Ibáñez de Navarra, Eugenio (Springer, 2019-05)
    Article

    This work proposes a fully Lagrangian formulation for the numerical modeling of free-surface particle-laden flows. The fluid phase is solved using the particle finite element method (PFEM), while the solid particles embedded ...
  • Multiscale proper generalized decomposition based on the partition of unity 

    Ibáñez Pinillo, Rubén; Ammar, Amine; Cueto Prendes, Elias; Huerta, Antonio; Duval, Jean Louis; Chinesta, Francisco (John Wiley & sons, 2019-06)
    Article
    Restricted access - publisher's policy
    Solutions of partial differential equations could exhibit a multiscale behavior. Standard discretization techniques are constraints to mesh up to the finest scale to predict accurately the response of the system. The ...
  • Out-of-equilibrium mechanochemistry and self-organization of fluid membranes interacting with curved proteins 

    Tozzi, Caterina; Walani, Nikhil; Arroyo Balaguer, Marino (2019-09-04)
    Article
    Open Access
    The function of biological membranes is controlled by the interaction of the fluid lipid bilayer with various proteins, some of which induce or react to curvature. These proteins can preferentially bind or diffuse towards ...
  • Converse flexoelectricity yields large piezoresponse force microscopy signals in non-piezoelectric materials 

    Abdollahi Hosnijeh, Amir; Domingo, Neus; Arias Vicente, Irene; Catalan, Gustau (2019-03-20)
    Article
    Open Access
    Converse flexoelectricity is a mechanical stress induced by an electric polarization gradient. It can appear in any material, irrespective of symmetry, whenever there is an inhomogeneous electric field distribution. This ...
  • Mechanotransmission of haemodynamic forces by the endothelial glycocalyx in a full-scale arterial model 

    Sáez Viñas, Pablo; Gallo, Diego; Morbiducci, Umberto (2019-06-05)
    Article
    Open Access
    The glycocalyx has been identified as a key mechano-sensor of the shear forces exerted by streaming blood onto the vascular endothelial lining. Although the biochemical reaction to the blood flow has been extensively ...
  • Rethinking the Kolmogorov-Smirnov test of Goodness of fit in a compositional way 

    Monti, Gianna S.; Mateu Figueras, Gloria; Ortego Martínez, María Isabel; Pawlowsky Glahn, Vera; Egozcue Rubí, Juan José (Pearson, 2018)
    Conference report
    Open Access
    The Kolmogorov Smirnov test (KS) is a well known test used to asses how a set of observations is significantly different from the probability model specified under the null hypothesis. The KS test statistic quantifies the ...
  • Self-sensing concrete made from recycled carbon fibres 

    Segura Pérez, Ignacio; Faneca Llesera, Gerard; Torrents Dolz, Josep M.; Aguado de Cea, Antonio (2019-10)
    Article
    Restricted access - publisher's policy
    The electrical and piezo-resistive responses of recycled carbon fibre (rCF)-reinforced concrete is analysed in this article. Two different PAN-based rCFs (monofilament rCF and fibrillated rCF sheets) incorporated into dry ...
