Modeling of fragmentation of rapidly expanding cylinders
|
|||
|
The paper considers fragmentation process of high-explosive projectile
casings, i.e. rapidly expanding cylinders loaded by extreme internal
pressure generated by detonation of explosives. The classical,
physically based, Mott model of the ring fragmentation is examined and
the adequate computer program is realized. The fragment size (or mass)
distribution is analyzed and the average fragment size is related to the
characteristics of expansion and the casing material properties. The
influence of the fragmentation process parameters on the nature of
fragment length distribution is analyzed. The theoretical distributions
