The Effects of C/M Ratio on the Controlled Fragmentation of Cylinders Using External Notching
Abstract
The effects of C/M (HE charge to cylinder mass) ratio on the degree of control of fragmentation exerted by external longitudinal notching are investigated. Two series of experiments are conducted. In one series the cylinder wall thickness is varied to induce weight scaling and in the other both the cylinder dimensions and notch pitching are varied to induce number scaling. Although both weight and number scaling with C/M ratio are feasible for notched cylinders, the results demonstrate that there are limitations to the degree of control exerted by the notching. Both weight and number scaling appear to be limited by the propensity for the operation of natural fragmentation mechanisms between the notches and weight scaling is also limited by geometric factors. The filling of the notches with an epoxy resin produces an increase in the degree of control of fragmentation for both weight and number scaling cylinders.
