Abstract
Experimental data on the fragmentation of copper shaped-charge jets are presented and the techniques used for data processing are described. A combined numerical/analytical analysis is designed to describe shaped-charge jet breakup. The method overcomes drawbacks from exclusively numerical or analytical analyses, such as mesh sensitivity or oversimplified description. It yields predictions for break-up time, total number, and cumulative length of fragments in fairly good agreement with the experimental data. The dependence of fragmentation characteristics on the grain size in the liner is also well predicted.
