“…For commercial blasting and many other applications that strength is important, the loading density is near unity. The Trauzl block method, which provides data at loading densities comparable to those used in practice, is the most widely used method for determining the strength of high explosives [1].…”

“…However for rock blasting, part of the energy of the products is expended in heating the rock and the other part remains in the products in the form of thermal energy. It should be mentioned that the energy expended in mechanical work is always lower than Q det and accounts for 70-80 % of it [1].…”

“…In another work [5], a correlation was introduced for prediction of the strength using the corrected Q det and specific impulse (I SP ). Afanasenkov [1] introduced another relationship to estimate volume expansion in the Trauzl lead block on the basis of Q det and volume of explosion products.…”

The strength of energetic materials is one of the principal parameters to express their performance. Two new methods were introduced for the prediction of the strength of CaHbNcOd energetic materials through the Trauzl test. They are based on elemental composition and the condensed or gas phase heats of formation of energetic compounds. The model is based on the gas phase heat of formation, uses the group additivity method and requires only the molecular structure of the desired energetic compound. These methods provide more reliable predictions as compared to the best available theoretical methods. Some of the benefits of these new models are their accuracy, precision, simplicity, and low price.

“…Thus, mechanical work in this case is always lower than Q det and accounts for 70-80 % of it. [3] The strength of an explosive also may be expressed as power index (f), which is defined as the ratio of its strength to the strength of a standard explosive, i.e. f = A/A st .…”

“…Since the Trauzl lead block method provides data at loading densities comparable to those used in practice, [7] it is the most widely used method for determining the strength of high explosives. [3] Since new energetic materials are usually not available in sufficient quantities or have not been synthesized yet, it would be worth to determine their performance parameters, like strength, by the theoretical methods. In Russia, different methods [3,8] have been developed for predicting the strength of commercial explosives.…”

Abstract. The strength of energetic materials can be expressed as the expansion of the cavity of a standard lead block through explosion of the sample. A new method is introduced for prediction of the Trauzl lead block expansions for some of the important classes of pure and mixture of energetic compounds, with the general formula ofThis model needs only the molecular structure of the energetic materials without using the detonation characteristics of different

A new method has been introduced to predict the power of important classes of energetic compounds including nitroaromatics, acyclic and cyclic nitramines, nitrate esters and nitroaliphatics. In this method, the predicted specific impulse and the corrected heat of detonation on the basis of H2O‐CO2 arbitrary decomposition, have been used to calculate the power of an explosive with the molecular formula CaHbNcOd as determined by the Trauzl test. The predicted results show good agreement with respect to the measured values for both pure and mixture of explosives. The calculated volume expansions of pure energetic compounds have a root mean square (rms) deviation of 33 cm3 from 73 measured values (corresponding to 58 molecules). For 9 explosive mixtures, the predicted volume expansions have an rms deviation of 39 cm3 from the experimental results.
