Fragmentation spectra of russian standard fragmenting cylinders made of new splintering 80G2S steel
The results of experimental studies of the process of splitting the Russian standard fragmenting cylinders (RSFC) of closed-type no. 12, made by punching of highly splintering steel 80G2S, are presented. The fragment masses that were obtained from tests of RSFC models filled with explosive materials of six types were statistically processed. The possibility of establishing correlations between the mass-numerical characteristics of the RSFC fragmentation spectra and the explosive material properties (the detonation velocity, the Chapman-Jouguet pressure, and the shell expansion velocity) according to the T-20 technique is shown. The application of the eutectoid 80G2S steel for mass production of the fragmenting and high-explosive shells, including those equipped with new plastisol explosive compounds that have a reduced sensitivity, is shown to be promising.
