  • Sliding joints in 3D beams: conserving algorithms using the master-slave approach 

    Muñoz Romero, José; Jelenic, Gordan (2006)
    Article
    Accés obert
    This paper proposes two time-integration algorithms for motion of geometrically exact 3D beams under sliding contact conditions. The algorithms are derived using the socalled master–slave approach, in which constraint ...
  • Hybrid cell-centred/vertex model for multicellular systems with equilibrium-preserving remodelling 

    Mosaffa, Payman; Rodríguez Ferran, Antonio; Muñoz Romero, José (John Wiley & sons, 2018-03)
    Article
    Accés restringit per política de l'editorial
    We present a hybrid vertex/cell-centred model for mechanically simulating planar cellular monolayers undergoing cell reorganisation. Cell centres are represented by a triangular nodal network, while the cell boundaries are ...
  • Proper generalized decomposition solutions within a domain decomposition strategy 

    Huerta, Antonio; Nadal Soriano, Enrique; Chinesta, Francisco (John Wiley & sons, 2018-03-30)
    Article
    Accés restringit per política de l'editorial
    Domain Decomposition strategies and the Proper Generalized Decomposition are efficiently combined to obtain a fast evaluation of the solution approximation in parameterized elliptic problems with complex geometries. The ...
  • A formulation for elastodynamic scattering based on boundary algebraic equations 

    Poblet-Puig, Jordi; Shanin, Andrey (Society for Industrial and Applied Mathematics (SIAM), 2018)
    Article
    Accés obert
    Solving of elastodynamic problems arises in many scientific fields such as wave propagation in the ground, non-destructive testing, vibration design of buildings, or vibroacoustics in general. An integral formulation based ...
  • Computation of forces from deformed visco-elastic biological tissues 

    Muñoz Romero, José; Amat Olóndriz, David; Conte, Vito (2018-04-01)
    Article
    Accés obert
    We present a least-squares based inverse analysis of visco-elastic biological tissues. The proposed method computes the set of contractile forces (dipoles) at the cell boundaries that induce the observed and quantified ...
  • Influence of contact angle boundary condition on CFD simulation of T-Junction 

    Arias Calderón, Santiago; Villardi de Montlaur, Adeline de (2018-03-15)
    Article
    Accés restringit per política de l'editorial
    In this work, we study the influence of the contact angle boundary condition on 3D CFD simulations of the bubble generation process occurring in a capillary T-junction. Numerical simulations have been performed with the ...
  • Geometric derivation of the microscopic stress: a covariant central force decomposition 

    Torres Sánchez, Alejandro; Vanegas, Juan Manuel; Arroyo Balaguer, Marino (2016-08)
    Article
    Accés restringit per política de l'editorial
    We revisit the derivation of the microscopic stress, linking the statistical mechanics of particle systems and continuum mechanics. The starting point in our geometric derivation is the Doyle-Ericksen formula, which states ...
  • An equilibrated fluxes approach to the certified descent algorithm for shape optimization using conforming finite element and discontinuous Galerkin discretizations 

    Giacomini, Matteo (2017-09-07)
    Article
    Accés restringit per política de l'editorial
    The certified descent algorithm (CDA) is a gradient-based method for shape optimization which certifies that the direction computed using the shape gradient is a genuine descent direction for the objective functional under ...
  • Towards the modelling of ageing and atherosclerosis effects in ApoE-/- mice aortic tissue 

    Waffenschmidt, T., Tobias; Cilla, Myriam; Sáez Viñas, Pablo; Pérez, Marta M.; Menzel, Andreas; Peña, E. (2016-08-16)
    Article
    Accés obert
    The goal of this work consists in a quantitative analysis and constitutive modelling of ageing processes associated to plaque formation in mice arteries. Reliable information on the characteristic evolution of pressure–stretch ...
  • Insertion of triangulated surfaces into a meccano tetrahedral discretization by means of mesh refinement and optimization procedures 

    Ruiz Gironès, Eloi; Oliver Serra, Albert; Socorro Marrero, Guillermo Valentín; Cascón Barbero, José Manuel; Escobar Sánchez, José M.; Montenegro Armas, Rafael; Sarrate Ramos, Josep (John Wiley & Sons, 2018)
    Article
    Accés restringit per política de l'editorial
    In this paper, we present a new method for inserting several triangulated surfaces into an existing tetrahedral mesh generated by the meccano method. The result is a conformal mesh where each inserted surface is approximated ...
  • A non-intrusive proper generalized decomposition scheme with application in biomechanics 

    Zou, Xi; Conti, Michele; Díez, Pedro; Auricchio, Ferdinando (John Wiley & Sons, 2017-09-07)
    Article
    Accés restringit per política de l'editorial
    Proper generalized decomposition (PGD) is often used for multiquery and fast-response simulations. It is a powerful tool alleviating the curse of dimensionality affecting multiparametric partial differential equations. ...
  • Generalized parametric solutions in Stokes flow 

    Díez, Pedro; Zlotnik, Sergio; Huerta, Antonio (2017-11-01)
    Article
    Accés restringit per política de l'editorial
    Design optimization and uncertainty quantification, among other applications of industrial interest, require fast or multiple queries of some parametric model. The Proper Generalized Decomposition (PGD) provides a separable ...
