heal.abstract	A desiccation theory is developed providing a rational framework for a three-dimensional analysis of shrinkage and crack formation in a stiff clay surface layer. With the present model, we are estimating the shrinkage stress and the chemical potential variation in a morpheme produced after cracking, in a stiff clay surface layer, in terms of measurable quantities. In regular shrinkage morphemes, the shrinkage stresses are calculated from the shrinkage displacement and moisture content change. Other parameters such as the water mobility are introduced in order to express the chemical potential and the entropy changes in terms of the moisture content change and temperature at various instants of time. © Springer-Verlag 2012.	en
