Impact-Induced Shock Propagation or Blast-Induced Shock Propagation is quite similar, and there are only differences in the boundary conditions of the problem. Fig. 3 shows impact absorption into a metal foam.

hock tubes are a tool for conducting explosive waves and simulating real explosions and their effects, which are usually used on a small scale. Shock tubes are also used to study the phenomena of compression flow and the combustion reaction of the gas phase. The shock wave inside a shock tube is generated by a small explosion (guided explosion) or by an increase in pressure that causes the diaphragm to collapse and propagate a compressed gas shock wave. Fig. 4 shows a picture of a laboratory explosive shock tube. S
