A Study on the Influencing Factors of Deformation Control of Deformable Warheads

Abstract:

The deformation processes of a deformable warhead was numerically simulated using LS-DYNA three-dimensional finite element code to determine the influence factors of deformation control on the deformation quality. The relationships among optimal deformation time interval, deformation chord length, and deformation control parameters were established. The result shows that the phase angle of deforming charge should be taken within the range of 60–90°. a larger deforming charge phase angle is favorable when it comes to increasing the fragment density in the target direction. Meanwhile, the thickness of deforming charge is less important than the phase angle in terms of the influence of the deformation chord-length.
