Modeling of fragmentation of rapidly expanding cylinders
Апстракт
The paper considers fragmentation process of high-explosive projectile casings, i.e. rapidly
expanding cylinders loaded by extreme internal pressures generated by detonation of
explosives. The classical Mott's model as well as the alternative approaches to the problem are
examined. The distribution laws of fragment size and mass are analyzed and the average fragment size (mass) is related to the characteristics of expansion and the casing material
properties. The theoretical distributions are compared with experimental data and good
correspondence is obtained. Finally, the possibilities for improvement of characteristics of
projectile fragmentation are investigated.
