Effect of grain size on brittle and semibrittle strength - Wiley Online .Jul 10, 1990 . Conversely, the effect of grain size on the strength and rheology of rocks at low temperatures is less well known. An inverse relationship between the plastic yield stress and grain size is well established in metals deformed at low temperatures. (i.e., those at which processes such as dislocation climb and.does particle size affect granite strength,Granite - WikipediaGranite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy. The word "granite" comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock.

Contiguity of the solid in solid-liquid mixture is primarily controlled by the volume fraction of the solid and the average wetting angle (q), and is secondarily affected by grain size distribution. Perhaps unexpectedly, contiguity is very insensitive to surface-energy anisotropy as manifested by non-spherical grain shape. Figure 9.
