Viggiani, Gioacchino; Hall, Stephen A.; Romero Morales, Enrique Edgar; Tudisco, E.; Musso, G.; Jommi, C.; Santamarina, J. Carlos (ALERT Geomaterials, 2012-10)
Llibre
Accés obertThe twenty-second session of the European Graduate School 2012 (called usually ALERT Doctoral School) entitled Advanced experimental techniques in geomechanics is organized by Cino Viggiani, Steve Hall and Enrique Romero. -
Experimental study of inelastic deformation at the micro scale in cemented granular materials: some recent results
Tengattini, Alessandro; Einav, Itai; Viggiani, Gioacchino (CIMNE, 2013)
Text en actes de congrés
Accés obertA novel thermomechanical constitutive model for cemented granular materials has been recently introduced. An essential ingredient of the model is the use of measurable and micro-mechanics based internal variables describing ... -
Image-based calibration of rolling resistance in discrete element models of sand
Rorato, Riccardo; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Andò, Edward; Viggiani, Gioacchino (Elsevier, 2021-03)
Article
Accés obertModels that introduce rolling resistance at the contact are widely employed in simulations using the discrete element method (DEM) to indirectly represent particle shape effects. This approach offers substantial computational ... -
Linking shape and rotation of grains during triaxial compression of sand
Rorato, Riccardo; Arroyo Alvarez de Toledo, Marcos; Andò, Edward; Gens Solé, Antonio; Viggiani, Gioacchino (2020-11)
Article
Accés obertParticle shape has a strong effect on the mechanical response of coarse soils. This has been usually observed examining specimen-scale or engineering-scale responses, which are the sum of many microscale interactions. In ...
