Dilatancy (granular material) - Wikipedia
WebIn soil mechanics, dilatancy is the volume change observed in granular materials when they are subjected to shear deformations. [1] [2] This effect was first described scientifically by Osborne Reynolds in 1885/1886 [3] [4] and is also known as Reynolds dilatancy.
Dilatant - Wikipedia
WebA dilatant is a non-Newtonian fluid where the shear viscosity increases with applied shear stress. This behavior is only one type of deviation from Newton's law of viscosity, and it is controlled by such factors as particle size, shape, and distribution.

WebJan 1, 2018 · Dilatancy is the property of soil material that refers to a change in its volume in response to shearing under a certain normal or confining stress. Context Soil material in an initially high relative density condition (low initial void ratio, e o ) will increase in volume (increase in void ratio) to a condition of constant volume with ...
