Abstract

ToexploretheformationmechanismoftandemEFP,experimentalandnumericalstudieson theformationprocessofshapedchargewithdoublelayerliners(SCDLL)intotandemEFPwerepresented. Fourtestsampleswithdifferentmaterialsweredesigned.Thesampleswereexperimentally testedtogetX-rayimages.Numericalsimulationswerethenperformedforthetestsamplesusing AUTODYN-2D.Basedontheexperimentalandnumericalinvestigations,analysiswasmadetofind thekeyfactorswhichinfluencetheformationprocessofSCDLL.ItisfoundthatSCDLLcanalways beseparatedintotwoprojectileswithcertainconfigurationandlinermaterials.Thecombinationof linermaterialandtheignitionpositionhavegreatinfluenceontheformationoftandemEFP.
