Recording the Onset of Detonation in the Depth of an Explosive by X-ray and Electric Contact Methods

Combustion, Explosion, and Shock Waves Aims and scope

Abstract

Results of experiments on loading flat samples of plastic-bonded HMX by a shock wave are presented. Recording is carried out via an X-ray method in which X-ray is triggered by a sensor that responds to the onset of detonation in a sample. The time and place of the onset of detonation and the influence of the initial density of the sample on these parameters are determined. Experimental results are reproduced in finite element calculations. A dependence between the computational model parameters and the initial density of the sample is obtained.
