Abstract: An experimental technique has been developed at Armour Research Foundation to determine, by means of photographic observation, the dynamic response of porous materials to very high rates of loading. In this experimental procedure, a metal plate is propelled by means of a controlled detonation of a thin layer of low-density high explosive in a manner to compress uniformly a specimen of the test material. A streak camera is used to record the motion of the metal plate and of the lines of a reference grid which is stencilled on the specimen. From the photographic records, one can directly observe the motion of the plate, the distortion of the specimen and the wave propagation in the specimen. Calculations are then easily made of the magnitude and attenuation of pressure pulses propagating in the specimen, the coefficient of restitution, and the stress-strain relationships for various rates of strain. The physical properties of a variety of porous media have been investigated by this technique.
