The Initial Velocities of Metal Plates Explosive-Driven from Asymmetric Sandwich

The Initial Velocities of Metal Plates Explosive-Driven from Asymmetric Sandwich

This paper presents modified Gurney formulas determining velocities of the explosive-driven metal plates which are parts of a flat asymmetric sandwich (AS). The modification takes into account a linear profile of the detonation products velocity in the Eulerian coordinates and a change of their dens...
