Effects of liner grain size on shaped – charge jet performance: A combined experimental/numerical/analytical approach


Experimental data on the fragmentation of copper shaped-charge jets are presented. A combined numerical/analytical analysis is designed to describe shaped-charge jet break-up. 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 in the liner grain size is well predicted, except for the leveling out of performances at very large grain size. A discussion is provided
