Abstract
From a model of transport of water in elastic medium [I. Mrani, J.-C. Benet, G. Fras, Transport of water in a biconstituant elastic medium, Appl. Mech. Rev., special issue on Mechanics of swelling 48 (1995) 717-721] the risk of craking induced by the water redistribution in a cylinder sample after drying is analysed. The numerical resolution of the transport equation of water and the mechanical equilibrium equation give access to the evolution of the water content, the deformation and the stresses in the medium. One will take interest in the state of material during drying, cooling and storage phases. At the end of this study, the risks of cracking are analyzed for various configurations of drying wich determine the hydrous state evolution during storage.
