Gurney velocity
WebJun 5, 2024 · A valid statistical dissipative property of the mesoscale discrete modeling with respect to Gurney velocity is demonstrated. The predicted surface expansion velocities can extend the time range of the velocity scaling law with regard to Gurney energy in the Gurney theory from the steady-state termination phase to the unsteady evolution phase. Webvelocity of flyer is a function of explosive to metal mass ratio and the Gurney energy of the explosive and a flyer can be launched to a maximum velocity of approx 5 km/s. An impact of a steel plate moving at 5km/s with the stationary steel plate generates a shock pressure of the order of 1.5 Mbar.
