There is no Newtonian plateau at intermediate shear rates, nor dilatancy
peak at higher shear rates.
5 that the volume strain depends on longitudinal strain rate, which implies that the dilatancy
phenomena of volume deformation depend on longitudinal strain rate.

The evolution of the dilatancy
, equation (8), is given by a function similar to that of the hardening modulus, with the sign of the function dictated by its distance to the dilatancy
stress so that
angle ([PSI]) can be approximated as [PSI] = [phi] -30[grados] (Material Models Manual of PLAXIS, 2012).

is a well-known phenomenon in frictional materials like concrete, soils, or masonry.
In the SC test, at the first stage of each loading step little dilatancy
takes place and dilatancy
begins to occur several minutes after step loading.

It analyzes phenomena such as shear thinning, dilatancy
, thixotropy, aging, emulsification, gelation, dissolvation, and flocculation in various products and texture types.

occurs when particles must spread apart in order to move past each other in response to a shear force applied to the material.
