The strength and dilatancy
of sands, Journal of Geotechnique 36(1): 65-78.
In order to capture the dilatancy
a model based on a linear complementarity formulation and a mathematical programming algorithm is enhanced in this paper.
Effect as a Specific Property of Periodicity of Gel Oxyhydrates
of samples under normal stress of 304 kPa were stopped, increased with a constant rate or decreased with further horizontal displacement.
This is a property of dilatancy
which is explained as a change in the distribution of solid phase particles and diminishing the liquid phase, i.
Examples of mechanisms that can cause dilatancy
are creaming of a solid or liquid phase, collision of sticky particles to form aggregates, and stress-activated phase separation.
2006) indicated that critical stated model was capable of simulating strain hardening, softening, normal dilatancy
and stress-path dependency of interface between sandy soil and structures during shearing.
shown between 0 and 2 L/D indicated particle rearrangement occurred when shear forces were first experienced by the loosely consolidated bed entering the solids-conveying region, while negligible compressive forces were present.

In suspensions of rigid particles such as clays, shearthickening and dilatancy
occur at high concentrations where the rigid particles are so closely packed that flow at increased shear rates must be accompanied by a concomitant movement of the particles thus creating stress-generated volume.
