Abstract
A one-dimensional Random Choice code has been developed for a medium of layered structure including solids and gases, and applied to the numerical simulation of explosive-driven cylindrical imploding shocks in solids. In the numerical experiments, imploding shocks in solids (aluminium, PMMA) are supposed to be generated by simultaneous detonations of cylindrical explosive (PETN) shells. Detonations are assumed to be initiated simultaneously from the outer surface of the PETN shells. The method of characteristics is adopted only for the flow calculation. The numerical results show that for some cases a negative pressure caused by the interference of the strong expansion waves emerges in the period after the shock is reflected on the axis. The total energy contained in the center region of the solid cylinder is compared with the chemical energy of the explosive.
