Abstract

A relatively simple method is explained, which makes it possible to determine the detonation velocity of an infinitely large charge, using a very small size sample. However, this requires additional instrumentation and a simple trick in the design of the sample. A prerequisite for this is that the detonation velocity of a reference high explosive must be known accurately and that this velocity is larger than that of the high explosive to be examined. By observing the front face, the true detonation velocity can then be determined, even with a very small sample size. The theoretical background, test set-up, and execution of the experiments are described below. Beside this special application, sandwiched explosive charges are of general interest in connection with shaped charge design, and generally in the effort to increase the efficiency of explosive energy transmission.
