Paper Abstract

Results of investigations of the rear side movement of RHA-plates under impact conditions are reported. Special emphasis is given to the rear side bursting processes, in an effort to get more detailed information about the time sequence of these processes and their mechanisms. By impact of thin disks and long rods, planar and hemispherical shock waves have been produced within the target plates. The rear side movement of the impact loaded plates was measured by means of a VISAR (Vqlocity Interferometer System for Any Reflector)-laser-interferometer. Thus, a quasi-continuous velocity-time-history of the whole process was obtained with a maximum time resolution of 5 nsec. The time sequence and the measured shock wave amplitudes of the rear side movement of the plate for the above mentioned loading conditions are completely different. This yields two different rear side fracturing mechanisms which will be discussed.
