The ballistic impact of a massive, effectively 1-D plate on an initially stationary foam layer is considered. It is shown that four discrete velocity regimes must be considered. Two of these regimes are of major interest for ballistic impact studies. Regime 2 considers the case when the initial velo

โฆ Synopsis
The work is devoted to investigation of metals' behavior under shock loading. The materials under investigation were copper, aluminum, lead, titanium, titanium alloys and different steels. Microstructure investigations have been carried out using optical microscopy. The strength behavior was investigated with the help of a microhardness device. Comparison of the spherical action of waves and uniaxial shock loading for the aforementioned metals has been done.

In impact ionization studies the target normally consists of a metal surface of compact solid density. In the present experiments, we investigate the use of a layer of a highly porous structure of nanometre-sized grains, sometimes also called ''metal black'', as an alternative target. In our compara
