A theory is given of the break-up of the metal case of a cylindrical ring-bomb, in which the lines of fracture perpendicular to the axis of the bomb are predetermined. From the theory an expression is given for the length of the average fragment; this is shown to depend, if certain hypotheses are made, on the radius and velocity of the case at the moment of break-up, and on the mechanical properties of the metal. 

Numerical Study of Ring Fragmentation

The fragmentation of rings and shells is a topic of enduring interest both because of the interesting dynamic conditions under which it takes places and the practical importance of fragmentation to

Spatial Distribution of Fragments of Explosively Loaded Thin-Walled Steel Cylinders

This paper describes the spatial distribution of fragments on static detonation of a thin-walled steel cylinder internally loaded with explosives. The fragments on striking a mild steel

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


Abstract : A technique to describe the mode of fragmentation and the vector velocity of the fragments from a center initiated cylindrical charge has been proposed in this program. The approach taken

Fragmentation in biaxial tension

We have carried out an experiment that places a ductile stainless steel in a state of biaxial tension at a high rate of strain. The loading of the ductile metal spherical cap is performed by the

Fragmentation model of a rapidly expanding ring with arbitrary cross-section

A model has been proposed to estimate the average number of fragments produced by ductile fracture of a rapidly expanding ring with arbitrary cross-section. The model uses a minimum number of

Statistics of dynamic fragmentation for a necking instability

In the aim of predicting the fragmentation of expanding structures, a Mott type approach is applied to the potential failure points driven from an instability analysis. Substantially, fragmentation
