Investigations of the Dynamic Properties of Matter Using Axis-Symmetrical ShockWaves

摘要

The technique for experiments with the cylindrical shock loading of ceramic tubesamples has been developed. In experiments, the shock loading of AD998 tubes was realized in two ways: by cylindrical detonation initiated by electrical explosion of wire and by impact of the stainless steel tube liner launched by the cylindrical detonation wave. The Lagrangian computer code for simulations of the shock-wave processes with axial symmetry has been developed and used for interpretation of experimental data. VISAR measurements of the velocity profiles have been carried out with water windows. Results do not correspond to the response of the elastic-plastic body and are the subject of forthcoming analysis.
