    • Effect of ageing and water action on the cracking resistance of asphalt mixtures 

      López Montero, Teresa; Miró Recasens, José Rodrigo; Pérez Jiménez, Félix Edmundo; Botella Nieto, Ramón (Springer, 2016)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Cracking in asphalt layers is one of the most frequent distress mechanisms in flexible pavements due to thermal stresses and traffic loads. Furthermore, the ageing phenomenon along with moisture damage are the key factors ...

    • Effect of bitumen type and content on the cracking resistance of asphalt mixtures at different temperatures 

      Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée; Pérez Jiménez, Félix Edmundo; Botella Nieto, Ramón (Springer, 2016)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Bitumen type and content are two of the variables that most influence on the cracking resistance of an asphalt mixture, since both determine a more or less ductile fracture. Furthermore, this cracking resistance will be ...

    • Estado de la resistencia a la fisuración de las mezclas bituminosas: ensayos Fénix y EBADE 

      Pérez Jiménez, Félix Edmundo; Miró Recasens, José Rodrigo; Martínez Reguero, Adriana Haydée; Botella Nieto, Ramón; Valdés Vidal, Gonzalo A. (2011-04)
      Article
      Accés obert
      Este artículo propone el empleo de dos ensayos desarrollados por el Laboratorio de Caminos de la Universidad Politécnica de Cataluña, uno estático de tracción (ensayo Fénix) y otro cíclico de tracción-compresión (ensayo ...

    • Experimental comparison of two testing setups for characterizing the shear mechanical properties of masonry 

      Segura Domingo, Jorge; Bernat Masó, Ernest; Mendizábal Dinucci, Virginia Dolores; Pelà, Luca; Roca Fabregat, Pedro; Gil Espert, Lluís (Elsevier, 2021-09-08)
      Article
      Accés obert
      The prediction of the structural capacity of masonry buildings against lateral loads requires an accurate characterization of the masonry strength and the general response under shear stresses. The experimental determination ...

    • Sources of error and limits of applying the energetic-based-regularization method 

      Aissaoui, N.; Matallah, M. (CIMNE, 2015)
      Comunicació de congrés
      Accés obert
      In this work, the energetic regularization technique based on the Crack Band approach is studied. The main objective is to identify the sources of errors related to the application of such technique under 2D and 3D ...

    • Structural size effect: experimental, theoretical and accurate computational assessment 

      Barbat Vlad, Gabriel; Cervera Ruiz, Miguel; Chiumenti, Michele; Espinoza Durán, Eduardo (Elsevier, 2020-06)
      Article
      Accés obert
      In this paper, experimental evidence, theoretical predictions and the finite element modelling of the structural size effect in cracking problems of quasi-brittle materials are discussed and assessed against each other. ...

    • Torque Penetrometric Test for the in-situ characterisation of historical mortars: fracture mechanics interpretation and experimental validation 

      Marastoni, Diego; Benedetti, Andrea; Pelà, Luca; Pignagnoli, Giacomo (2017-12)
      Article
      Accés obert
      The assessment of historical structures requires appropriate knowledge of the behaviour of the investigated materials. Concerning masonry, its mechanical characterisation is a challenging task, since its composite nature ...
