Abstract
Aimedatfragmentpenetrationintofluidcabinbulkhead,atheoreticalanalysismodelwas
establishedtoexplorethepenetrationprocessofwater-backedtargets.Basedontheenergyanalysis,a
formulafortheresidualvelocityofthefragmentafterthewater-backedtargetpenetrationwasderived
bycombiningthemotionequationandtheDeMarremodel.Thederivedformulawasappliedtocalculatetheresidualvelocitiesofthefragmentswiththeinitialvelocitiesof1.0~
1.6km/s.Andthepenetrationprocessofthefragmentsintothewater-
backedtargetwasmodeledbyusingthenon-lineardynamicsanalysissoftware,
AUTODYN.Theresidualvelocitiesbythederivedformulaareinagreementwiththosebythesoftware,
AUTODYN.Theresidualvelocitiesobtainedabovewerecompared
withthosebytheexistentformulaforthefragmentswiththesameinitialvelocitiesaftertheairbackedtargetpenetration.
Comparisonshowsthatthefluidbehindthebulkheadcanpreventfragment

backedtargetpenetration.Thehigherthe
initialvelocityofthefragment,thegreaterthefluidresistance,theclearerthevelocityattenuation.
