Abstract
Results of experiments on loading flat samples of plasticized 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.
