摘要：

The generation of defects as a phenomenon of structure self-organization under the action of an external energy flux was investigated on an example of compression of a solid nanostructure. It is shown that there exists a critical energy flux at which the system experiences an avalanche change both in the time- and load-dependence of energy absorption and in the type of wave processes in its structure.
