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)
Text en actes de congrés
Accés restringit per política de l'editorialThis 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 ... -
Marchetti flat dilatometer tests in a virtual calibration chamber
Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Amoroso, Sara; Gens Solé, Antonio (2018-09)
Article
Accés obertCalibration chambers are frequently used to verify, adapt, or both verify and adapt empirical relations between different state variables and in situ test results. Virtual calibration chambers (VCC) built with 3D discrete ... -
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
Accés restringit per política de l'editorialA 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)
Text en actes de congrés
Accés restringit per política de l'editorialA 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'editorialThe 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'editorialVirtual 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 obertThe 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'editorialIt 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'editorialThe 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 ...
