X c is a characteristic size (size modulus) and γ c is a constant which defines the relative width of the distribution (distribution modulus). In accordance with the definitions of fracture and attrition, values of X c are fairly close to the size y of the particle being broken for fracture, and very much less than y for attrition. Some examples of these distributions are given in Fig. 2.
