Abstract

Djelovanje gospodarskih eksploziva moguće je opisati raznim veličinama za čije utvrđivanje postoje brojne metode ispitivanja. Postoje metode koje se izvode na terenu, odnosno in situ, i one čija provedba zahtjeva laboratorijske uvjete. Svaka od njih daje rezultate koji su empirijskog, teoretskog ili kombiniranog karaktera. Pojedine metode su opisane u radu. Metoda određivanja učinka djelovanja eksplozije putem ekspanzije metalne cijevi odnosno cilindra, osim empirijskih podataka dobivenih mjerenjima, u kombinaciji s konceptom Gurneyjeve energije daje i teoretske zaključke o djelovanju eksploziva. Brojnim ispitivanjima temeljenim na toj metodi potvrđena je i njena široka primjena koja se odnosi na međusobnom uspoređivanju svojstava eksploziva, ali i na optimizaciji svojstava eksplozivnih smjesa.

Abstract (english)

The effects of commercial explosives can be described in various sizes, for which there are numerous test methods. There are methods performed in the field, that is, in situ, and those whose implementation requires laboratory conditions. Each of them produces results that are empirical, theoretical, or combined. Some methods are described in the paper. The method of determining the effect of an explosion through the expansion of a metal tube or cylinder, except empirical data obtained from measurements, combined with the concept of Gurney energy, also gives theoretical conclusions about the action of explosives. Numerous tests based on this method have confirmed its widespread application, which relates to the comparison of the properties of explosives, but also to the optimization of the properties of explosive mixtures.
