    • Analysis and modeling of unsteady effects within the wheel-rail contact 

      Diaz de la Fuente, Sergio (Universitat Politècnica de Catalunya / Technische Universität Graz, 2011)
      Master thesis (pre-Bologna period)
      Open Access
      The traction characteristic of the wheel-rail contact is of high importance, e.g., for vehicle dynamics, and for the transmission of forces during traction and braking. This characteristic is influenced by fast changes of ...
    • Estudio experimental del coeficiente de rozamiento entre dovelas prefabricadas de hormigón para puentes con junta seca conjugada 

      Ruiz Ripoll, Lidia; Barragán, Bryan E.; Lozano Galant, José Antonio; Turmo Coderque, José (Asociacion Científica del Hormigón Estructural (ACHE), 2011)
      Conference report

      Este trabajo de investigación permite solventar la carencia de datos experimentales sobre los coeficientes de rozamiento de juntas de dovelas prefabricadas de hormigón sometidas a compresiones mayores a 5 MPa y corroborar ...
    • Friction coefficients and wear rates of different orthodontic archwires in artificial saliva 

      Alfonso, M.V.; Espinar, Eduardo; Llamas, José María; Rupérez de Gracia, Elisa; Manero Planella, José María; Barrera, J.M; Solano, E.; Gil Mur, Francisco Javier (Springer, 2013-05)
      Article
      Restricted access - publisher's policy
      The aim of this paper is to analyze the influence of the nature of the orthodontic archwires on the friction coefficient and wear rate against materials used commonly as brackets (Ti–6Al–4V and 316L Stainless Steel). ...
    • Identification of a system with dry friction 

      Iurian, Claudiu; Ikhouane, Fayçal; Rodellar Benedé, José; Griñó Cubero, Robert (2005-09)
      External research report
      Open Access
      A new elasto-plastic state variable friction model is proposed which models both stiction and presliding displacement. However, the proposed Leuven model by Swevers et al. is more complex than the standard parameterization ...
    • Modeling and identification of a small scale magnetorheological damper 

      Aguirre Carvajal, Naile; Ikhouane, Fayçal; Rodellar Benedé, José; Wagg, David; Neild, Simon (2010)
      Conference lecture
      Open Access
      Magnetorheological (MR) dampers are promising vibration control devices widely used for vibration mitigation applications as they combine reliability and stability of passive systems while maintaining versatility of active ...
    • Modelling unilateral frictionless contact using the null-space method and cubic B-Spline interpolation 

      Muñoz Romero, José (2008-02)
      Article
      Open Access
      The analysis of unilateral sliding contact in elasticity is equivalent to a minimisation problem subjected to a set of inequality constraints. However, the presence of boundary discontinuities, such as those stemming from ...
    • Short-cut method to assess a gross available energy in a medium-load screw friction press 

      Sánchez Egea, Antonio José (Multidisciplinary Digital Publishing Institute (MDPI), 2018-03-10)
      Article
      Open Access
      The present study proposed a rapid method, based on a previous universal compression tests, to estimate the required load capacity to cold forge different specimen quantity in a screw press. Accordingly, experimental and ...
