Abstract

Abstract

In this study we carried out internal blast tests on TNT, PBXN-109, AFX-757 and CL-20 based explosives and measured the concrete cavity volumes of several explosives tested to study the characteristic work capability of non-ideal explosives. A calculation model of the concrete cavity volume was established on the basis of dimensional analysis and experimental dada. The characteristic work capacity of test explosives was evaluated using self-designed concrete cavity volume method. The results show that the concrete cavity volume can be used to evaluate the work capability of non-ideal explosives. The concrete cavity volume and the explosive energy (or detonation heat) forms a linear relationship. The relative work capacity of the explosive in concrete can be determined by the TNT equivalent of the detonation heat.
