INVESTIGATION OF THE PROPAGATION OF A SHOCK WAVE IN MATERIALS WITH THE ACCOUNT OF THEIR HETEROGENEITY

The investigation of the heterogeneous material response on microscopic level at a high speed load is the aim of the paper as well as the investigation of non-linear effects, induced by shock-wave interactions. As a result a parameter, making it possible to describe quantitatively the modification of the energy density at the propagation of a package of solitons, has been introduced. Laws of the propagation of solitons in a heterogeneous medium have been established. It has been shown, that the influence of a distorted plane form of a shock wave front on the material response may lead to effects of microfragmentation and to the origin of disordered fields. The possibility of the formation of a nanocrystalline structure for amorphous materials at a shock-wave load has been forecastedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
