CREEP MECHANISMS IN CLAY

The processes involved in creep are strongly dependent on the micro-structural constitution of clays. Shearing produces a translation and rotation of rigid aggregates in connection with a break-down of a certain number of particle links which are transformed to slip units consisting of groups of parallel flaky particles. A physical clay model therefore implies that an element of clay contains a certain number of slip units in a given interval of the activation energy range. This suggests that a mathematical formulation of creep strain rate in clay can be based on stochastic models similar to those suggested for metals and alloys. The application is briefly discussed in the paper. /TRRL/
