    • Influence of cracking in the desiccation process of clay soils 

      Levatti, Hector Ulises; Prat Catalán, Pere; Ledesma Villalba, Alberto (2009)
      Text en actes de congrés
      Accés obert
      It is well known that clayey soils undergoing desiccation tend to shrink and eventually crack. Analysis of the behaviour and influence of cracks in these types of soils is very important in several engineering fields such ...

    • Numerical analysis of desiccation, shrinkage and cracking in low plasticity clayey soils 

      Levatti, Hector Ulises; Prat Catalán, Pere; Ledesma Villalba, Alberto (CIMNE, 2017)
      Text en actes de congrés
      Accés obert
      This paper presents a numerical study of the desiccation processes of low-plasticity clayey soils that usually result in shrinkage and often in cracking. For the theoretical development of the numerical model, concepts of ...

    • Numerical and experimental study of initiation and propagation of desiccation cracks in clayey soils 

      Levatti, Hector Ulises; Prat Catalán, Pere; Ledesma Villalba, Alberto (Elsevier, 2019-01)
      Article
      Accés obert
      This paper presents the fundamentals and the mathematical formulation to study desiccation cracking in soils based on Unsaturated Soil Mechanics as well as a numerical analysis of a previous desiccation test program. The ...

    • Simulación numérica de procesos de desecación en suelos cohesivos de baja plasticidad 

      Levatti, Hector Ulises (Universitat Politècnica de Catalunya, 2012-11-20)
      Tesina
      Accés obert
      La retracción y agrietamiento de suelos cohesivos es un fenómeno complejo de caracterizar y estudiar. La simulación numérica es una herramienta potente que permite dilucidar y comprender cuales son los mecanismos básicos ...
