Dilatancy (granular material) - Wikipedia
Dilatancy is a common feature of soils and sands. Its effect can be seen when the wet sand around the foot of a person walking on beach appears to dry up. The deformation caused by the foot expands the sand under it and the water in the sand moves to …

Dilatancy is the volume change observed in granular materials when they are subjected to shear deformations. This effect was first described scientifically by Osborne Reynolds in 1885/1886 and is also known as Reynolds dilatancy .
Dilatancy - SpringerLink
2018年1月1日 · 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 ...

Dilatancy for cohesionless soils - Géotechnique
2000年8月4日 · Dilatancy is often considered a unique function of the stress ratio η = q/p′, in terms of the triaxial stress variables q and p′. With this assumption, the direction of plastic flow is uniquely related to η, irrespective of the material internal state.
Dilatancy - an overview | ScienceDirect Topics
The presence of dilatancy can significantly enhance the stability of a rock mass, especially when rock blocks or wedges are placed between dilatant joints. Under the constrained normal displacement condition, dilatancy can lead to an increase in normal stress and thus the shear strength of the joint during shear.
Dilatancy Toughening of Shear Cracks and Implications for Slow …
2021年11月4日 · Dilatancy is a well documented process in intact, healed or overconsolidated rocks: due to shear deformation, microcavities (cracks, grain junctions) open, which induces an overall increase in porosity (Paterson & Wong, 2005, Section 5.3). In fluid saturated rocks, this increase in porosity has the potential to induce fluid pressure drops if ...
DILATANCY在剑桥英语词典中的解释及翻译 - Cambridge Dictionary
dilatancy. Dilatancy is the change of overall volume produced by strain in an assembly of particles. The very thin veins that developed in clay-rich areas suggest that they episodically underwent dilatancy. This relates to a property of granular materials under pressure called the " principle of dilatancy".
Dilatancy Characteristics of Soil - ScienceDirect
1974年9月1日 · ABSTRACT. The formulas of the relationship between stress ratios and strains due to dilatancy derived from the microscopic analysis based on observation of the particulate nature of soil (Matsuoka, 1973; Matsuoka, 1974) have been verified with respect to the measured data of drained triaxial compression and extension tests on sand and clay.
