      Viggiani, Gioacchino; Hall, Stephen A.; Romero Morales, Enrique Edgar; Tudisco, E.; Musso, G.; Jommi, C.; Santamarina, J. Carlos (ALERT Geomaterials, 2012-10)
      Book
      Open Access

    • Experimental study of inelastic deformation at the micro scale in cemented granular materials: some recent results 

      Tengattini, Alessandro; Einav, Itai; Viggiani, Gioacchino (CIMNE, 2013)
      Conference report
      Open Access
      A 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
      Restricted access - publisher's policy
      Models 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
      Open Access
      Particle 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 ...
