  • 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 ...
