    • Patterns of cracking in soils due to drying and wetting cycles 

      Ledesma Villalba, Alberto; Cordero Arias, Josbel Andreina; Cuadrado Cabello, Agustín; Prat Catalán, Pere (CRC Press, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      There is a well reported evidence of cracking in clayey or silty soils when drying. Shrinkage in the soil mass and also boundary conditions generate a nonhomogeneous stress state locally producing tensile stresses and ...
    • Soil surface boundary condition in desiccating soils 

      Cuadrado Cabello, Agustín; Encalada López, David Alejandro; Ledesma Villalba, Alberto; Prat Catalán, Pere (The Icelandic Geotechnical Society (IGS), 2019)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Soils undergoing desiccation exhibit shrinkage and eventually cracking. That may become an environmental problem in practical applications. From a Geotechnical perspective, it is possible to solve the corresponding ...
    • THM analysis of a soil drying test in an environmental chamber: the role of boundary conditions 

      Cuadrado Cabello, Agustín; Najdi, Abdallah; Ledesma Villalba, Alberto; Olivella Pastallé, Sebastià; Prat Catalán, Pere (Elsevier, 2022-01)
      Article
      Accés obert
      This paper presents the numerical analysis of an experimental soil drying test carried on an initially slurry soil specimen with controlled temperature and relative humidity in a laboratory environmental chamber. The imposed ...
    • Towards the development on new high capacity tensiometers capable of measuring soil matric suction beyond 3 MPa 

      Mendes, Joao; Najdi, Abdallah; Encalada López, David Alejandro; Prat Catalán, Pere; Ledesma Villalba, Alberto (2022-09)
      Article
      Accés obert
      High capacity tensiometers (HCT) are the only type of sensors in existence that can measure soil matric suction directly and are regarded to be the most accurate and reliable technique for the study of suction evolution ...
    • Transient large heat advection in fractured rock: a zero-thickness interface formulation 

      Pérez Carreras, Adrià; Carol, Ignacio; Prat Catalán, Pere (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
      Text en actes de congrés
      Accés obert
      In a fractured rock mass, the existence of discontinuities may generate preferential paths where the hydraulic flow velocities are frequently much higher than in the porous medium and heat advection tends to dominate over ...
