Rapid expansion of metallic cylinder driven by internal explosive detonation
Апстракт
The paper considers acceleration of a cylindrical liner caused by expanding products of internal detonation. A new model of liner motion is developed for the cases of axisymmetric (head-on) and grazing (side-on) detonation of the explosive charge. Suggested model relies on the two-stage regime of cylinder motion: (i) the first stage is the consequence of detonation wave – metallic liner interaction; as a result the initial velocity is imparted to the liner, (ii) the second stage is gas-dynamic push of the liner governed by detonation product expansion, similarly to the Gurney model. The model completely describes the cylinder motion in the cases of axisymmetric and quasi-steady grazing detonation. Comparison with extensive database of experimental results shows that proposed model provides very good description of measured data in the domain relevant for terminal ballistics applications.
