The results of experimental studies of physical reasons and conditions of the phenomenon of energy focusing in explosion systems including high modulus elastic elements are presented. Experiments were conducted to study the conditions of this phenomenon for TG-40/60, SEP and Composition B. For each HE a number of experiments has been conducted for various heights of silicon carbide inserts. Presence or absence of a hole in the steel specimen was determined. Also a number of frame-by-frame recordings of the process with record step of 1 μs have been performed. It is shown that the energy focusing phenomenon is reproduced for various high explosives. The phenomenon is observed in the conditions close to critical conditions of detonation transfer from an active to a passive HE charge. The best conditions for the phenomenon were observed for TG-40/60 for ceramic insert heights of 16.5 mm, 18 mm and 19.5-mm. Physical reason of focusing process is the propagation of a concave detonation wave into highly compressed HE and the formation of a Mach stem on the axis of HE charge. [ABSTRACT FROM AUTHOR] |
