Abstract

Clay has a creep behavior; its deformation develops slowly with time under constant magnitude of stress. Therefore, the stress-strain curve of clay varies with the rate of loading. When loaded faster, clay reveals greater modulus and higher strength. These observation suggests that clay is a viscous material.

On the other hand, the stress-strain-strength characteristics of clay is controlled by a grain-to-grain friction and chemical bonding as well as electric interaction. The magnitude of these forces are not much dependent of the rate of loading. Consequently, the stress-strain behavior of clay is partially rate-dependent but partially rate-independent.
