Abstract

BasedonthenonlineardynamicssoftwareLS-DYNA,thecompleteprocessofjetparallel penetratingair/steeltargetinterfacewasnumericallysimulated.Byanalyzingtheprocessandresultof numericalsimulation,thevelocityoftheshapedchargejettipandthetransversevelocityafterimpact werediscussed.Theresultsshowthatattheair/steeltargetinterfacetheaxialvelocityoftheshaped chargejettipdecreasesevidentlyandtheshapedchargejettipisreducedtomovingtransversely,the highesttransversevelocityofwhichisabout1.8km/s;thatthetransversevelocitiesofthesubsequentjetsdecreasegraduallyandthejetdisruptionisantedated. Consequently,theair/steeltargetinterfacecanmarkedlydisturbtheshapedchargejettipandeffectivelyweakenthejetpenetration.
