Brief Description of Technology The study of the characteristics of condensing material in high dynamic load conditions (with the pressure up to 200 GPa). Expected in the study are: a) Experimental modeling of dynamic conditions of any degree of difficulty; b) Study of results of these conditional influences by modern methods of solid state physics; c) Construction of strain maps, the study of localized deformation phenomena, mass moving plus the phase and structure transformations in the material; d) Mathematical and computer modeling of nonlinear processes, in accordance with stay of sample in extreme physical conditions based upon experimental data.

Legal Aspects Unique equipment was used in the study. This equipment has been developed by VNIITF. Given equipment allowed to save samples, which were subjected to action of high dynamic pressure and temperature. Processes, that running under significant gradients of temperature and pressures, in the broad range of thermodynamic parameters, can be study on the one sample. Research potential VNIITF allows to get experimental data required for making of models of any degrees of difficulty. Explorative base and theoretical models of IMP allow to realize investigations on the high level.

Special Facilities in Use and Their Specifications Unique equipment allowed to save samples, which were subjected to action of high dynamic pressure and temperature.
