Typical Velocity-Density Curves for AN-Combustible Mixtures

Belyaev observed (Ref 8, p 293) that for weaker expls, such as mixts contg AN, the relationship betw critical diameter dc and loading density pQ does not resemble that given for TNT in Fig 88 (Our Fig 7). In most of these expls critical diameter increases with. increase of density, as can be seen from Fig 89, p 294 of Ref 8 (Our Fig 12), where curve 1 is for Dinamon (AN 88 8t peat 12%) 

The dotted line indicates the region of failure of detonation 

In the book of Andreyev Belyayev (Ref 9, p 197-98) are given critical diameters of some explosives. See Tables III IV 

Results of work of Russian investigators have also shown the following  

The smallest influence of confinement is for initiating expls and for brisant expls of high density and large diameter of chge
