Abstract

The desiccation cracks can be often observed on dry-out soil surfaces. These cracks have a net-like structure and tessellate the surface of the material into polygonal cells hierarchically. The size and the shape of these cells on the final pattern change systematically depending on the specimen thickness and the constraint conditions. In this paper, firstly, we perform the drying experiments of calcium carbonate slurry. Then, we propose the coupled model of desiccation, deformation, and fracture for the problem of the desiccation cracking and perform the weak coupling analysis of the finite element method and particle discretization scheme finite element method. The results of the numerical analysis show the satisfactory agreement with the experimental observation in terms of the process of the crack pattern formation and the change in size of the cells corresponding to the thickness of the specimen.
