dilatanciának
Dilatancy is a phenomenon observed in granular materials where the volume of the material increases when it is sheared. This means that as the material is deformed, its constituent particles move apart, creating more empty space between them. This effect is particularly noticeable in dense granular packings. When subjected to shear stress, the particles are forced to ride over each other, leading to an expansion of the bulk material.
The term "dilatancy" comes from the Latin word "dilatare," meaning to expand or spread out. It was
Dilatancy is a key characteristic of non-Newtonian fluids, specifically those classified as shear-thickening. In such fluids,
