Simulation Results

In this paper, a new mechanism of plasma radiation optics-ammunition inspired by electrically exploding wires blasting in inert gases is studied. The simulation results indicate that, plasma radiation intensity increased by Mach-number of shock waves, and in all insert gases, argons Mach-number of shock waves is the highest. Silver is the best in common metal materials, and the exploding time and current peak is about linear with the number of wires. And the simulation results agree with the known experiment data and are important to the study of strong pulsed IR optics-ammunition.

Deformation Velocity

Single crystals of Al were loaded by 15 to 40 GPa shock waves at 77 K with a pulse duration of 1.0 to 0.5 μs and a residual deformation of ∼1%. The analysis of deformation structure peculiarities allows the deformation history to be re-established.After a 20 to 40 GPa loading the dislocation density in the recovered samples was about 1010 cm-2. By measuring the thickness of the 40 GPa shock front in Al, a plastic deformation velocity of 1.07 x 108 s-1 is obtained, from where the moving dislocation density at the front is 7 x 1010 cm-2. A very small part of dislocations moves during the whole time of compression, i.e. a total dislocation density at the front must be in excess of this value by one or two orders. Consequently, due to extremely high stresses, at the front there exists a very unstable structure which is rearranged later with a noticeable decrease in dislocation density.
