  • A nonlinear rotation-free shell formulation with prestressing for vascular biomechanics 

    Nama, Nitesh; Aguirre Font, Miquel; Humphrey, Jay D.; Figueroa, C. Alberto (Springer, 2020-10-16)
    Article
    Accés obert
    We implement a nonlinear rotation-free shell formulation capable of handling large deformations for applications in vascular biomechanics. The formulation employs a previously reported shell element that calculates both ...
  • An upwind vertex centred Finite Volume solver for Lagrangian solid dynamics 

    Aguirre Font, Miquel; Antonio Javier, Gil; Bonet Carbonell, Javier; Lee, Chun Hea (2015-11-01)
    Article
    Accés obert
    A vertex centred Jameson–Schmidt–Turkel (JST) finite volume algorithm was recently introduced by the authors (Aguirre et al., 2014 [1]) in the context of fast solid isothermal dynamics. The spatial discretisation scheme ...
  • A first order hyperbolic framework for large strain computational solid dynamics. Part I: total Lagrangian isothermal elasticity 

    Bonet Carbonell, Javier; Antonio Javier, Gil; Lee, Chun Hea; Aguirre Font, Miquel; Ortigosa, Rogelio (Elsevier, 2015-01-01)
    Article
    Accés obert
    This paper introduces a new computational framework for the analysis of large strain fast solid dynamics. The paper builds upon previous work published by the authors (Gil et al., 2014) [48], where a first order system of ...
  • A stabilised Petrov–Galerkin formulation for linear tetrahedral elements in compressible, nearly incompressible and truly incompressible fast dynamics 

    Gil, Antonio J.; Chun Hean, Lee; Bonet Carbonell, Javier; Aguirre Font, Miquel (Elsevier, 2014-07-01)
    Article
    Accés obert
    A mixed second order stabilised Petrov–Galerkin finite element framework was recently introduced by the authors (Lee et al., 2014) [46]. The new mixed formulation, written as a system of conservation laws for the linear ...
  • Effect of foot stato-dynamic disorders on hemodynamics of the lower limb using strain-gauge plethysmography 

    Tsimba, Laure; Rastel, Didier; Dechandon, Emilie; Vincent, Patrick; Micholet, Céline; Chaigneau, Cyril; Avril, Stephane; Aguirre Font, Miquel (Elsevier, 2023-11)
    Article
    Accés restringit per política de l'editorial
    Background: The plantar venous pump (PVP), composed of deep plantar veins, is the most distal contributor to venous return from the lower limbs. A pressing need still exists to assess how plantar muscle contraction and ...
  • Patient-specific computational modelling of endovascular treatment for intracranial aneurysms 

    Bisighini, Beatrice; Aguirre Font, Miquel; Pierrat, Baptiste; Avril, Stephane (Elsevier, 2023-12)
    Article
    Accés obert
    Endovascular techniques, such as endoluminal or endosaccular reconstruction, have emerged as the preferred method for treating both ruptured and unruptured intracranial aneurysms, replacing open surgery in most cases. The ...
  • Patterning and dynamics of membrane adhesion under hydraulic stress 

    Dinet, Céline; Torres Sánchez, Alejandro; Lanfranco, Roberta; Di Michele, Lorenzo; Arroyo Balaguer, Marino; Staykova, Margarita (2023-12-01)
    Article
    Accés obert
    Hydraulic fracturing plays a major role in cavity formation during embryonic development, when pressurized fluid opens microlumens at cell-cell contacts, which evolve to form a single large lumen. However, the fundamental ...
  • CRIMSON: an open-source software framework for cardiovascular integrated modelling and simulation 

    Arthurs, Christopher J.; Khlebnikov, Rostislav; Melville, Alex; Marcan, Marija; Gomez, Alberto; Dillon-Murphy, Desmond; Cuomo, Federica; Silva Vieira, Miguel; Schollenberger, Jonas; Lynch, Sabrina R.; Tossas-Betancourt, Christopher; Iyer, Kritika; Aguirre Font, Miquel (Public Library of Science (PLOS), 2021-05-10)
    Article
    Accés obert
    In this work, we describe the CRIMSON (CardiovasculaR Integrated Modelling and SimulatiON) software environment. CRIMSON provides a powerful, customizable and user-friendly system for performing three-dimensional and ...
  • OpenFOAM numerical analysis of the diurnal cycle of thermally-driven winds on Mars 

    Arias Calderón, Santiago; Rojas Gregorio, José Ignacio; Villardi de Montlaur, Adeline de (2023)
    Text en actes de congrés
    Accés obert
    The study of Martian winds holds significant scientific interest and potential practical applications. For instance, understanding the dynamics and behaviour of Martian winds is crucial in order to properly evaluate and ...
  • Domain-driven multiple-criteria decision-making for flight crew decision support tool 

    Villardi de Montlaur, Adeline de; Delgado Muñoz, Luis; Prats Menéndez, Xavier (Elsevier, 2023-09-01)
    Article
    Accés obert
    During the flight, the crew might consider modifying their planned trajectory, taking into account currently available information, such as an updated weather forecast report or the already accrued amount of delay. This ...
  • On the numerical stability of discretised optimal control problems 

    Bijalwan, Ashutosh; Muñoz Romero, José (Springer, 2024-01-05)
    Capítol de llibre
    Accés obert
    Optimal Control Problems (OCP) consist in optimising an objective functional subjected to a set of Ordinary Differential Equations. In this work, we consider the effects on the stability of the numerical solution when this ...
  • Topology optimization of flexoelectric metamaterials with apparent piezoelectricity 

    Greco, Francesco; Codony Gisbert, David; Mohammadi, Hossein; Fernández Méndez, Sonia; Arias Vicente, Irene (Elsevier, 2024-02-01)
    Article
    Accés obert
    The flexoelectric effect, coupling polarization and strain gradient as well as strain and electric field gradients, is universal to dielectrics, but, as compared to piezoelectricity, it is more difficult to harness as it ...
