  • 3D DEM simulations of CPT in sand 

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2012)
    Conference report

    The paper contains an overview of the results obtained in a research project exploring the ability of 3D DEM models to reproduce cone penetration in sands. The sand whose behaviour is mimicked by the discrete material ...
  • Cone penetration test in a virtual calibration chamber 

    Butlanska, Joanna (Universitat Politècnica de Catalunya, 2014-07-21)
    Doctoral thesis
  • Cone penetration tests in a virtual calibration chamber 

    Arroyo Alvarez de Toledo, Marcos; Butlanska, Joanna; Gens Solé, Antonio; Calvetti, Francesco; Jamiolkowski, Michael (2011)
    Article
    Restricted access - publisher's policy
    A virtual calibration chamber was built using a threedimensional model based on the discrete-element method. The chamber was then filled with a scaled granular equivalent of Ticino sand, the material properties of which ...
  • DEM modelling of a double-porosity crushable granular material 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Butlanska, Joanna; Gens Solé, Antonio (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    The effect of grain crushing during one dimensional compression and triaxial compression tests is investigated in a double-porosity granular material using the Discrete Element Method (DEM). Experimental tests results from ...
  • Homogeneity and symmetry in DEM models of cone penetration 

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (American Institute of Physics (AIP), 2009)
    Conference report
    Restricted access - publisher's policy
    A three—dimensional numerical model was implemented to PFC3D Code to simulate cone penetration test in Ticino sand in a calibration chamber. The model is calibrated using laboratory test results. The full/half/quarter ...
  • Mapping deformation during CPT in a virtual calibration chamber 

    Butlanska, Joanna; O'Sullivan, C.; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (CRC Press/Balkema, 2010)
    Conference report
    Restricted access - publisher's policy
    This paper analyses results from a three dimensional discrete element method simulation of the cone penetration test in a "Virtual Calibration Chamber" (VCC). The deformation patterns in the soil adjacent to the cone ...
  • Multi-scale analysis of cone penetration test (CPT) in a virtual calibration chamber 

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; O'Sullivan, Catherine (2014-01)
    Article
    Restricted access - publisher's policy
    A virtual calibration chamber was developed using a three-dimensional (3D) discrete element method (DEM) to perform cone penetration tests (CPTs) on a discrete analogue of Ticino sand. The macroscale response of the DEM ...
  • 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)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • Size effects on a virtual calibration chamber 

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (CRC Press. Taylor & Francies Group, 2010)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • Steady state of solid-grain interfaces during simulated CPT 

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2013)
    Article
    Restricted access - publisher's policy
    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)
    Conference report
    Restricted access - publisher's policy
    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 ...
