Abstract
The effects of warhead radial confinement on the performance of an EFP were studied. Wavecode modeling, range testing and analysis of six confinement thicknesses in a fixed volume warhead were investigated. The wavecode predictions of the EFP shapes agreed well with the x-ray silhouettes and recovered EFPs from the range tests. The maximum EFP temperature predictions from modeling also agreed well with the results of metallurgical analysis of the recovered EFPs. Finally, the dependence of EFP performance on confinement thickness was defined.
