A toughness related parameter, Asv, of monocrystalline, amorphous, and finely polycrystalline brittle materials is derived from standard sedimentologic size analysis of a crushed sample. Asv is numerically equal to the area under the cumulative-frequency size distribution curve and is related to the fracture toughness, Kc, of the material by the relationship, Asv = 202 + 383 log Kc.

A study of quartz shows that toughness generally increases with decreasing grain size and with an increasing degree of interlocking of the grains or fibers.
