Abstract

Thebendingoftheprojectileintheprocessofhigh-speedpenetratingconcreteisstudiedby simplifyingtheprojectileasafree-freebeam.Thebending momentcausedbythetransverseload whichisgeneratedfromsmallangleofattackandpenetrationresistanceisanalyzedthroughtheoreticalwork. Theanalysisshowedthatthetheoreticalbendingconditionisdominatedbyinitialstatus, structureandmaterialoftheprojectile.Thecomputedresultsprovedthatthebendingofhigh-speed penetratingprojectileisaffectedbytheexistenceofsmallangleofattack.Thepenetrationexperiment alsoindicatesthatthebendingpositionandthebendingconditionobtainedfromexperimentresultsare wellagreedwiththeoreticalanalysis.
