Master thesis (pre-Bologna period)
Open AccessThe 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 (Asociacion Científica del Hormigón Estructural (ACHE), 2011)
Restricted access - publisher's policyEste 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 ...
Restricted access - publisher's policyThe 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). ...

Open AccessA 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 ...
Open AccessMagnetorheological (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 (2008-02)
Open AccessThe 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 ...
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-03-10)
Open AccessThe 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 ...
