  • Multiscale computational homogenization: review and proposal of a new enhanced-first-order method 

    Otero Gruer, Fermín Enrique; Oller Martínez, Sergio Horacio; Martínez García, Javier (2016-11-25)
    Article
    Accés restringit per política de l'editorial
    The continuous increase of computational capacity has encouraged the extensive use of multiscale techniques to simulate the material behaviour on several fields of knowledge. In solid mechanics, the multiscale approaches ...
  • The curious arithmetic of optical vortices 

    Molina Terriza, Gabriel; Recolons Martos, Jaume; Torner Sabata, Lluís (2000-08-15)
    Article
    Accés restringit per política de l'editorial
    The superposition of noncoaxial light beams containing screw wave-front dislocations is shown to create light patterns with a richer vortex content than that given by the arithmetic of the topological charges of the ...
  • Guided to leaky mode transition in uniaxial optical slab waveguides 

    Torner Sabata, Lluís; Recolons Martos, Jaume; Pérez Torres, Juan (1993-10)
    Article
    Accés obert
    The guided-to-leaky hybrid mode transition in slab optical waveguides made on uniaxial crystals such as LiNbO/sub 3/, or LiTaO/sub 3/, is analyzed. Two different guided-to-leaky transitions have been identified, namely the ...
  • Lagrangian finite element model for the 3D simulation of glass forming processes 

    Ryzhakov, Pavel; García Espinosa, Julio; Oñate Ibáñez de Navarra, Eugenio (2016-12)
    Article
    Accés restringit per política de l'editorial
    We propose here a numerical model for a three-dimensional simulation of glass forming processes. Using the basic philosophy of the Particle Finite Element method (PFEM), we introduce several new features adapting the ...
  • A laminated structural finite element for the behavior of large non-linear reinforced concrete structures 

    Escudero Torres, Cuauhtemoc; Oller Martínez, Sergio Horacio; Martínez García, Javier; Barbat Barbat, Horia Alejandro (2016-10)
    Article
    Accés restringit per política de l'editorial
    In order to correctly predict the kinematics of complex structures, analysis using three-dimensional finite elements (3DFEs) seems to be the best alternative. However, simulation of large multi-layered structures with many ...
  • Impact of logistics and shipping in the sustainable development of societies 

    Martínez Marín, Jesús Ezequiel (Constanta Maritime University, 2011-11-10)
    Article
    Accés obert
    Definitely, although not very obvious, shipping affects the daily lives of the majority of the world population. The socio-economic implications of logistics undoubtedly affect the social development of cities. With the ...
  • Validation on large scale tests of a new hardening–softening law for the Barcelona plastic damage model 

    Barbu, Lucia Gratiela; Martínez García, Javier; Oller Martínez, Sergio Horacio; Barbat Barbat, Horia Alejandro (2015-12-01)

  • An efficient multi-scale method for non-linear analysis of composite structures 

    Otero Gruer, Fermín Enrique; Martínez García, Javier; Oller Martínez, Sergio Horacio; Salomon Rotlisbeger, Ramon Omar (2015-11-01)
    Article
    Accés obert
    The use of multi-scale procedures is encouraged by the continuous increase of computational capacity, but it is still a challenge performing a non-linear analysis of real composite structures without the aid of large ...
  • A FEM fluid-structure interaction algorithm for analysis of the seal dynamics of a Surface-Effect Ship 

    García Espinosa, Julio; Capua, Daniel di; Serván Camas, Borja; Ubach Fuentes, Pere-Andreu; Oñate Ibáñez de Navarra, Eugenio (2015-10-01)
    Article
    Accés obert
    This paper shows the recent work of the authors in the development of a time-domain FEM model for evaluation of the seal dynamics of a surface effect ship. The fluid solver developed for this purpose, uses a potential flow ...
  • Development of a decision support system for optimization of the performance of sailing yachts 

    García Espinosa, Julio; Ortigosa Barragán, Inma; Fernandez, A (2015-01-01)
    Article
    Accés obert
    In this paper, the conception and design of a new monitoring system for a racing yachts rig is presented. The sensors developed are able to process the measured strain data, by applying artificial neural networks (ANN) ...
