The nanocomposites (NC) are applied in the many spheres of the mechanical engineering, because they have mechanical and other properties, which the tradional materials have not. But for realization of their high operational quality it is necessary to raise the prognosis level of their properties. This is stipulated for high dependence their physical and rnechanical properties on the condition and "history" of compression processes. There are many factors which influence for the NC properties: the composites mechanical properties, friction between the composites materials and the technological tools, inner friction the type of compresison, temperature, speed of loading etc. The experimental investigations of the influence described above factors on the quality composites materials demand many time and resources, that is why the numerical simulations of the forming processes are very urgent.

The scopes of present papers were to do develop numerical investigation of the mechanics processes in NC (some results of the previous research are shown in [1,2]). For this purpose the finite elements method was used.
 By means of the numerical calculations the kinetics of the NC compression processes and distribution of inner material parameters were investigated. Also, the complex compression processes of thee materials, the formation of the parts by means of the loading direction change, multistep press processes, the compression of the material with different mechanical properties were analyzed.
