Desiccation cracks prediction using a 3D finite elements model
This paper focuses on the cracking of fine soil grains by desiccation using a 3D hydro-mechanical model. It further seeks to study the cracks growth across the depth during the desiccation time. Numerical results provide data for assessing the depth propagation of the cracks, field suction in 3D, the tensile stresses caused by the cracks. Cross sections have been considered to determine the cracks’ depth. Furthermore, water content and suction versus time have been obtained. It is still challenging to experimentally obtain a sample’s suction, water content, and distribution of stresses. Although there is a gap between numerical and experimental results concerning the appearance time of the first crack, the interpretation given in the text demonstrates that it is a wrong gap. Consequently, it can be stated that the numerical results agree with the experimental results, in terms of cracks intensity factor (CIF) and the evaporation rate as functions of desiccation time.
