Dec 08, 2016 It is shown that blast fragmentation data in the form of sets of percentile fragment sizes, x P, as function of specific charge powder factor, q often form a set of straight lines in a logx P versus logq diagram that tend to converge on a common focal point. This is clear for single-hole shots with normal specific charge values in specimens of virgin material, and the phenomenon is ...
