Abstract

Basedonthemodeofductileholeexpansion,theChen-and-LimodelandForrestal-and-Warrenmodelwereanalyzedforarigidsharp- nosedprojectileperforatingductilemetallictargetplates.Analysisshowsthatthesetwomodelshavethesameformula, buttheirapplicablerangesaredifferent whichisduetotheiremployingthecylindricalcavityexpansiontheoryandsphericalcavityexpansion theory,respectively.Andthesetwomodelswerecomparedwiththeexperimentalresultsfromthe perforationofaluminumplatesbyrigidsharp-nosedprojectiles.Thetheoreticalresultsbythesetwo modelsareinagreementwiththeexperimentalresults.
