【 摘 要 】

Studies of constructional material behavior under pulse power densities are very important both for fundamental researches and different applications. Modeling of shock wave generation in porous composites is complicated task because of complex structure of such materials. It is necessary to have rather detailed experimental database for verification of these models. In this paper, we present experiments that were carried out on high current electron accelerator "Calamary". We investigated the surface plasma expansion and mechanical kick pulse dependence from different energy fluxes. Also irradiated targets were investigated by electron microscope.
