A new efficient strategy to simulate particle breakage in DEM analyses
Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Calvetti, Francesco (2014)
Text en actes de congrés
Accés restringit per política de l'editorialThe discrete element method (DEM) is increasingly gaining acceptance as a modelling tool for engineering problems of direct geotechnical relevance. One area for which the method seems naturally well adapted is that of ... -
A new strategy to simulate particle crushing in DEM analysis
Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Calvetti, Francesco (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
Text en actes de congrés
Accés obertThe discrete element method (DEM) is progressively gaining acceptance as a modelling tool for engineering problems of direct geotechnical relevance. One area for which the method seems naturally well adapted is that of ... -
A numerical investigation of the incremental behavior of crushable granular soils
Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Calvetti, Francesco; Gens Solé, Antonio (2016-09)
Article
Accés obertThe mechanical behavior of granular materials is characterized by strong nonlinearity and irreversibility. These properties have been differently described by a variety of constitutive models. To test any constitutive ... -
An Approach to enhance efficiency of DEM modelling of soils with crushable grains
Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Calvetti, Francesco; Gens Solé, Antonio (Thomas Telford, 2015-02)
Article
Accés obertIn this study oedometric compression tests of hydrocarbon coke, Fontainebleau sand and silica sand are simulated in three dimensions using breakable particles. The method adapts a rigorous breakage criterion for elasto-brittle ... -
Cone penetration tests in a virtual calibration chamber
Arroyo Alvarez de Toledo, Marcos; Butlanska, Joanna; Gens Solé, Antonio; Calvetti, Francesco; Jamiolkowski, Michael (2011)
Article
Accés restringit per política de l'editorialA 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 ... -
