Velocities of acceleration of plates made of different materials by detonation products

Velocities of acceleration of plates made of different materials by explosion products from the end face of a small-thickness charge are measured. Velocities of acceleration of non-porous metal plates with an identical mass, made of aluminum, steel, copper, and tantalum differ by less than 5%. The difference in velocities of acceleration of porous plates made of the same materials and plates with an identical mass but made of several layers of different materials reaches 20%. Layered plates with aluminum layers of different porosities can be accelerated to higher velocities than solid plates. No decrease in velocity is observed in the case with a talcum layer placed under a steel plate of the same thickness, i.e., with an increased total mass. The effects observed can be explained by the wave approach to considering the process of plate acceleration.
