Cyclic Compaction Under Alternate Shear Motion
The basic phenomenon of granular materials compaction under alternate shear motion is commonly experienced in daily life with everyday granular materials of all kinds, for example in filling to maximum a jar with raw sugar, coarse salt, dry rice, and so on. In geomaterials, this well‐known phenomenon has been documented by specific experimentations for a long time. It is widely used in civil works for improving the consistency of granular fills used as infrastructure platforms such as highways and rail track platforms, rockfill dams, and so on, with the means of static or vibratory roller compactors. This chapter presents a simplified model of this phenomenon through the macroscopic dissipation equation under quasi‐static conditions. It analyses the basic features of the dissipation relation, regarding the effect of quasi‐static strain‐driven alternate shear motion cycles, small enough to maintain stress variations negligible relative to their average values.
