Abstract:
An explosively formed penetrator (EFP) with fins has the advantages of stable flight and deep penetration. On the basis of analyzing several possible approaches to form an EFP with fins, a three-dimensional numerical simulation using the AUTODYN-3D software was carried out on two typical structures including special cases and multi-point ignition. Then, EFPs with satisfactory shapes were obtained. The calculation results can be used in the design of EFP warheads.
