    • Elementos finitos de alto orden para problemas con interfaces materiales 

      Barceló Mercader, Jordi (Universitat Politècnica de Catalunya, 2017-01)
      Bachelor thesis
      Restricted access - author's decision
      La solució de problemes amb intefícies materials és en l'actualitat un problema de gran interés. El mètode eXtended Finite Elements permet resoldre aquests tipus de problemes sense necessitat d'una malla que s'adapti a la ...
    • Geometrically polarized architected dielectrics with apparent piezoelectricity 

      Mocci, Alice; Barceló Mercader, Jordi; Codony Gisbert, David; Arias Vicente, Irene (2021-12)
      Article
      Open Access
      Through the suitable geometry of a repeating unit, a metamaterial can exhibit a property not present in the base material. Here, we propose a class of low area-fraction, bending-dominated metamaterials that exhibit apparent ...
    • Mathematical and computational modeling of flexoelectricity 

      Codony Gisbert, David; Mocci, Alice; Barceló Mercader, Jordi; Arias Vicente, Irene (2021-12-21)
      Article
      Open Access
      We first revisit the mathematical modeling of the flexoelectric effect in the context of continuum mechanics at infinitesimal deformations. We establish and clarify the relation between the different formulations, point ...
    • Numerical solution of PDEs in periodical domains 

      Barceló Mercader, Jordi (Universitat Politècnica de Catalunya, 2018-01)
      Master thesis
      Open Access
      We present in this work two schemes of approximation for numerical solutions of PDEs. The first one is the maximum entropy method (max-ent) and the second one is the b-spline method. These methods let us impose a special ...
    • Weak enforcement of interface continuity and generalized periodicity in high-order electromechanical problems 

      Barceló Mercader, Jordi; Codony Gisbert, David; Fernández Méndez, Sonia; Arias Vicente, Irene (John Wiley & sons, 2022-02-28)
      Article
      Open Access
      We present a formulation for the weak enforcement of continuity conditions atmaterialinterfacesinhigh-orderproblemsbymeansofNitsche’smethod,whichis particularly suited for unfitted discretizations. This formulation is ...
