  • Simulating squeeze flows in multiaxial laminates: towards fully 3D mixed formulations 

    Ibáñez, Rubén; Abisset-Chavanne, Emmanuelle; Chinesta, Francisco; Huerta, Antonio (2016-07)
    Article
    Accés restringit per política de l'editorial
    Thermoplastic composites are widely considered in structural parts. In this paper attention is paid to squeeze flow of continuous fiber laminates. In the case of unidirectional prepregs, the ply constitutive equation is ...
  • Algebraic and parametric solvers for the power flow problem: towards real-time and accuracy-guaranteed simulation of electric systems 

    García Blanco, Raquel; Díez, Pedro; Borzacchiello, Domenico; Chinesta, Francisco (2017-04-25)
    Article
    Accés restringit per política de l'editorial
    The power flow model performs the analysis of electric distribution and transmission systems. With this statement at hand, in this work we present a summary of those solvers for the power flow equations, in both algebraic ...
  • Enhanced goal-oriented error assessment and computational strategies in adaptive reduced basis solver for stochastic problems 

    Serafin, Kevin; Magnain, Benoît; Florentin, Eric; Parés Mariné, Núria; Díez, Pedro (John Wiley & Sons, 2017-05-04)
    Article

    This work focuses on providing accurate low-cost approximations of stochastic ¿nite elements simulations in the framework of linear elasticity. In a previous work, an adaptive strategy was introduced as an improved Monte-Carlo ...
  • Generation of curved high-order meshes with optimal quality and geometric accuracy 

    Ruiz Gironés, Eloi; Sarrate Ramos, Josep; Roca Navarro, Xevi (2016)
    Article
    Accés obert
    We present a novel methodology to generate curved high-order meshes featuring optimal mesh quality and geometric accuracy. The proposed technique combines a distortion measure and a geometric L2-disparity measure into a ...
  • Bulging brains 

    Weickenmeie, J.; Sáez Viñas, Pablo; Butler, C. A.; Young, P.G.; Gorily, A.; Kuhl, Ellen (2016-10)
    Article
    Accés restringit per política de l'editorial
    Brain swelling is a serious condition associated with an accumulation of fluid inside the brain caused by trauma, stroke, infection, or tumors. It increases the pressure inside the skull and reduces blood and oxygen supply. ...
  • Hierarchical micro-adaptation of biological structures by mechanical stimuli 

    Sáez Viñas, Pablo; Pena, Estefanía; Doblaré, Manuel; Martínez, Miguel Ángel (2013)
    Article
    Accés obert
    Remodeling and other evolving processes such as growth or morphogenesis are key factors in the evolution of biological tissue in response to both external and internal epigenetic stimuli. Based on the description of these ...
  • An anisotropic microsphere-based approach for fiber orientation adaptation in soft tissue 

    Sáez Viñas, Pablo; Pena, Estefanía; Doblaré, Manuel; Martínez, Miguel Ángel (2011)
    Article
    Accés obert
    Evolutionary processes in biological tissue, such as adaptation or remodeling, represent an enterprising area of research. In this paper, we present a multiscale model for the remodeling of fibered structures, such as ...
  • On the use of the Bingham statistical distribution in microsphere-based constitutive models for arterial tissue 

    Alastrué, V.; Sáez Viñas, Pablo; Martínez, M.A,; Doblaré, Manuel (2010)
    Article
    Accés obert
    Constitutive models for arterial tissue have been an active research field during the last years. The main micro-constituents of blood vessels are different types of cells and the extra-cellular matrix formed by an isotropic ...
  • Mechanics reveals the biological trigger in wrinkly fingers 

    Sáez Viñas, Pablo; Zöllner, A. M. (2017-04)
    Article
    Accés restringit per política de l'editorial
    Fingertips wrinkle due to long exposure to water. The biological reason for this morphological change is unclear and still not fully understood. There are two main hypotheses for the underlying mechanism of fingertip ...
  • Anisotropic microsphere-based approach to damage in soft fibered tissue 

    Sáez Viñas, Pablo; Alastrué, V.; Pena, Estefania; Doblaré, Manuel; Martínez, Miguel Ángel (2012-05)
    Article
    Accés obert
    An anisotropic damage model for soft fibered tissue is presented in this paper, using a multi-scale scheme and focusing on the directionally dependent behavior of these materials. For this purpose, a micro-structural or, ...
