Fragment shape distribution in explosively driven fragmentation
Апстракт
The paper considers the shape distribution of fragments generated by detonation of a fragmentation warhead. Determination of the fragment shape distribution is very important for analysis of fragment ballistics and then for treatment of fragment interaction with a target. Morphology of metal fragments originating from casings of high-explosive projectiles is examined. Subsequently, the idealized fragment geometry and shape parameters are defined. Two theoretical models of fragment shape distribution are presented: (a) the model based on Mott’s two-dimensional fragmentation approach, and (b) the Curran’s “slot machine” model. The results of both models are transformed into previously defined shape parameters. Theoretical results are shown to be in good agreement with available experimental data.
