A probabilistic after-effect analysis of relaxation in clays
In the analysis of the constitutive performance of clay soils, it has been generally assumed that the material can be evaluated and examined in the light of continuum theory. However, detailed study of clays reveals that the rigid clay particles in the soil-water system do not act individually, but flocc together to form larger “particles” which are identified as fabric units (1, 2). In a recent study, some account of this phenomenon has been noted (3, 4). However, in view of the heterogeneity of the overall system, and the wide distribution of fabric units, concern must be directed towards the integrity of individual fabric units.
