  • Numerical Study and Experimental Comparison of Two-Phase Flow Generation in a T-Junction 

    Arias Calderón, Santiago; Villardi de Montlaur, Adeline de (2017)
    Article
    Accés obert
    This paper presents a three-dimensional numerical study of the bubble generation process in a micro T-junction, performed with the commercial computational fluid dynamics solver ANSYS Fluent, version 15.0.7. Numerical ...
  • Computational model of collagen turnover in carotid arteries during hypertension 

    Sáez Viñas, Pablo; Peña, Estefanía; Tarbell, J.M.; Martínez, Miguel Angel (John Wiley & Sons, Ltd, 2015-02)
    Article
    Accés obert
    t is well known that biological tissues adapt their properties because of different mechanical and chemical stimuli. The goal of this work is to study the collagen turnover in the arterial tissue of hypertensive patients ...
  • A theoretical model of the endothelial cell morphology due to different waveforms 

    Sáez Viñas, Pablo; Malve, M.; Martínez, M.A. (2015-08)
    Article
    Accés obert
    Endothelial cells are key units in the regulatory biological process of blood vessels. They represent an interface to transmit variations on the fluid dynamic changes. They are able to adapt its cytoskeleton, by means of ...
  • Microstructural quantification of collagen fiber orientations and its integration in constitutive modeling of the porcine carotid artery 

    Sáez Viñas, Pablo; García, A.; Peña, Estefanía; Gasser, Thomas Christian; Martínez, M.A. (2016-03)
    Article
    Accés restringit per política de l'editorial
    Background Mechanical characteristics of vascular tissue may play a role in different arterial pathologies, which, amongst others, requires robust constitutive descriptions to capture the vessel wall’s anisotropic and ...
  • On the theories and numerics of continuum models for adaptation processes in biological tissues 

    Sáez Viñas, Pablo (2016-06)
    Article
    Accés restringit per política de l'editorial
    Computational continuum mechanics have been used for a long time to deal with the mechanics of materials. During the last decades researches have been using many of the theoretical models and numerical approaches of classical ...
  • Porous-based rheological model for tissue fluidisation 

    Asadipour, Nina; Trepat, Xavier; Muñoz Romero, José (2016-11-01)
    Article
    Accés restringit per política de l'editorial
    It has been experimentally observed that cells exhibit a fluidisation process when subjected to a transient stretch, with an eventual recovery of the mechanical properties upon removal of the applied deformation. This ...
  • Collective cell durotaxis emerges from long-range intercellular force transmission 

    Sunyer, Raimon; Conte, Vito; Escribano, Jorge; Elosegui Artola, Alberto; Labernadie, Anna; Valon, Leo; Navajas Navarro, Daniel; Garcia Aznar, José Manuel; Muñoz Romero, José; Trepat, Xavier (2016-09-09)
    Article
    Accés obert
    The ability of cells to follow gradients of extracellular matrix stiffness—durotaxis—has been implicated in development, fibrosis, and cancer. Here, we found multicellular clusters that exhibited durotaxis even if isolated ...
  • Fourth order phase-field model for local max-ent approximants applied to crack propagation 

    Amiri, Fatemeh; Millán, Daniel; Arroyo Balaguer, Marino; Silani, Mohammad; Rabczuk, Timon (2016-12)
    Article
    Accés restringit per política de l'editorial
    We apply a fourth order phase-field model for fracture based on local maximum entropy (LME) approximants. The higher order continuity of the meshfree LME approximants allows to directly solve the fourth order phase-field ...
  • Computational modeling of acute myocardial infarction 

    Sáez Viñas, Pablo; Kuhl, E. (Gordon and Breach Science Publishers, 2016-07)
    Article
    Accés restringit per política de l'editorial
    Myocardial infarction, commonly known as heart attack, is caused by reduced blood supply and damages the heart muscle because of a lack of oxygen. Myocardial infarction initiates a cascade of biochemical and mechanical ...
  • Elliptic harbor wave model with perfectly matched layer and exterior bathymetry effects 

    Modesto Galende, David; Fernandez Mendez, Sonia; Huerta, Antonio (2016-09)
    Article
    Accés obert
    Standard strategies for dealing with the Sommerfeld condition in elliptic mild-slope models require strong assumptions on the wave field in the region exterior to the computational domain. More precisely, constant bathymetry ...
