REGULARITIES IN THE FORMATION OF STRUCTURAL STATES AND HYDRODYNAMIC FLOWS IN COPPER AND STEEL AT THE COLLAPSE OF CYLINDRICAL SHELLS UNDER THE EXPLOSION ACTION

DOI: 10.17804/2410-9908.2018.5.018-037

The collapse of copper and steel shells (pipes) into solid cylinders under the action of explosion is investigated. The phase and structural transformations occurring in materials affected by high-speed deformation during collapsing are studied; fracture phenomena associated with the release of a shock wave onto the free inner surface of the shell are investigated. It is shown that the convergence of shells of large diameter proceeds more steadily; it is established that the stability of convergence depends on the absolute dimensions of the shell rather than on the relative ones. It is shown that comparing the results of experiments on collapsing shells from various materials makes it possible to recreate partially the loading conditions that were not recorded directly in the experiment, in particular, to calculate the mass velocity of the shell and the pressure in the front of the shock wave.

Acknowledgments: The submicroscopic study was performed with the equipment of the Nanotechnologies and Advanced Materials Testing Center collective use center of IPM UB RAS. The work was supported by the UB RAS Complex Program (project 18-10-2-39).

Keywords: collapse of shells, high-speed deformation, shock-wave loading, copper, steel, microstructure
