    • SBPM testing in Bothkennar clay: structure effects 

      Arroyo Alvarez de Toledo, Marcos; González, Nubia Aurora; Butlanska, Joanna; Gens Solé, Antonio; Dalton, C (Taylor & Francis, 2008)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A series of self-boring pressuremeter tests performed in Bothkennar clay are simulated using a finite element model of undrained cavity expansion. A bonded elasto plastic soil model is employed to represent Bothkennar clay ...

    • Simulation of the cone penetration test: discrete and continuum approaches 

      Gens Solé, Antonio; Arroyo Alvarez de Toledo, Marcos; Butlanska, Joanna; Monforte Vila, Lluís; Carbonell, J.M.; Ciantia, Matteo Oryem; O'Sullivan, Catherine (Australian Geomechanics Society, 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The paper presents the modelling of the cone penetration test using two procedures: a discrete approach and a continuum approach. The discrete approach is based on the Discrete Element Method where a granular material is ...

    • Size effects on a virtual calibration chamber 

      Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (CRC Press. Taylor & Francies Group, 2010)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Virtual Calibration Chambers (VCC) are 3D-DEM models where cone penetration is simulated. They offer the possibility of substituting for the rather more expensive physical calibration chambers. One important issue in ...

    • Standard penetration testing in a virtual calibration chamber 

      Zhang, Ningning; Arroyo Alvarez de Toledo, Marcos; Ciantia, Matteo Oryem; Gens Solé, Antonio; Butlanska, Joanna (Elsevier, 2019-07)
      Article
      Accés obert
      The virtual calibration chamber technique, based on the discrete element method, is here applied to study the standard penetration test (SPT). A macro-element approach is used to represent a rod driven with an impact like ...

    • Steady state of solid-grain interfaces during simulated CPT 

      Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2013)
      Article
      Accés restringit per política de l'editorial
      It has recently been shown (Arroyo et al. [1]) that 3D DEM models are able to reproduce with reasonable accuracy the macroscopic response of CPT performed in calibration chambers filled with sand. However, the cost of ...

    • Virtual Calibration Chamber CPT on Ticino sand 

      Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2010)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The following paper surnmarizes results of CPT's performed in virtual calibration chamber (VCC) built with a 3D model based on the distinct element method (DEM). A discrete material tailored to mimic Ticino sand is tested ...
