Abstract: The effect of shell material (copper and silicon carbide) on the detonation of a cylindrical explosive charge was analyzed. The wave patterns in both the detonation products and the shells are substantially different, which is due to different sound velocities and the rapid destruction of ceramics under explosive loading. The wave pattern at the explosive/ceramic interface was found to have features associated with the desensitization of the explosive due to its loading by the leading wave from the shell side and manifested in a decrease in pressure, blurring of the detonation front, and an increase in mass velocity. Throughout the process, there is a continuous increase in the time of explosive decomposition near the interface of the explosive and the ceramic shell. An extended region with a constant pressure close to Chapman–Jouguet pressure was observed on the axis of symmetry behind the detonation front of the explosive charge in the ceramic shell.
Keywords: unsteady detonation, high-modulus ceramics, desensitization, shear waves.
