Abstract
During a laboratory experimental campaign (related to the PhD thesis of the first author) on soil cracking due to drying, several unseen morphological observations were made. Cracks were observed at the bottom of the desiccating specimen apart from the usual cracks at the drying exposed surface. The cracks observed at the bottom are a particularly interesting pattern of fissures, which is different from the one observed at the top specimen. That complicates the analysis of crack development, and...
