Current interest in investigating impacts of thin structural plates by pellets traveling at velocities of 15 kmsec and above has prompted efforts to simulate the process under laboratory conditions. Pellet and plate debris vaporization that results from such impacts cannot be achieved in the laboratory. A partial laboratory simulation of these impacts can be achieved by substituting easily vaporized materials such as cadmium for the structural materials of direct interest. The AFML Impact Physics Group has developed a series of techniques for carrying out such simulations. Besides measurements of gross damage effects, the velocity, mass, and momentum distributions within the simulated debris clouds can be measured as functions of time after impact. A limited number of typical results for cadmium-on-cadmium impacts are presented.
