Drying induced stresses estimated on the base of elastic and viscoelastic models

The main subject of this paper is to study how the chosen constitutive model of a saturated porous body undergoing drying process influences the numerically estimated drying induced stresses and deformations. To compare the results one assumes the material of a convectively dried cylinder to be both elastic and viscoelastic. One states a significant difference between the results obtained for both these models, particularly for the drying induced stresses. (C) 2002 Published by Elsevier Science B.V.
