The destruction of an energetic condensed system based on glycerol trinitrate, polyether urethane, and an aluminum powder from exposure to a relativistic electron beam with a maximum energy of 310 keV, a total duration of 170 ÷ 180 ns, and an average flux density of 200 ÷ 215 J/cm2 was studied by nanosecond electron-optical chronography, scanning electron microscopy, and energy dispersive analysis. The effect of the generation of pulsed electric fields and shock-wave loads accompanying relativistic electron beam absorption on the mechanical damage in samples of energetic condensed systems is discussed.
