Loading of obstacles by explosion of a low-density sheet explosive

The dependence of the detonation velocity of a NIL-1 low-density sheet explosive on density is found in the range of charge densities 0.1–0.3 g/cm$^3$. The equation of state of the NIL-1 detonation products with a linear dependence of the effective isentropic exponent of unloading on the density of an explosive that is acceptable for applied calculations is proposed. Calculated estimates of the mechanical action of an NIL-1 explosion on obstacles from several powerful explosive compositions are given.
