Abstract

Aimedatformingmultimodepenetratorswiththesameshapedcharge,theLS-DYNAsoftwarewasusedtoexploretheeffectsofthepointinitiationpositionontheformationofanexplosively formedpenetrator(EFP).Whentheaxisdistancebetweenthelinerandtheinitiationpointincreased from0to0.72timesaslongasthechargecaliber,theEFPvelocityincreased37.8percentandthe length-diameterratioincreasedover100percent.Thechargeshapewasoptimized.Thediffusionof thedetonationwaveswasanalyzed,whichwereformedbythecenterpointinitiationattheendofthe chargeandthepointinitiationofthelinerpeak,respectively.Andtheconversionoftherod-shaped EFPandEFPwasachieved.ThesimulatedresultsaccordwiththeX-rayimagingexperiments.
