Aimedatnormalandobliquepenetrationintosemi-infiniteconcrete/limestonetargetsbya high-speedprojectile,anaxisdragforcewasemployedtoreflectthecontinuousvariationofthenose shape.Withconsideringthetransverseloadinthecasesofasymmetricalmassabrasionandoblique penetration,amethodwasproposedtoanalyzetheyieldofanormally/obliqulypenetratingprojectile. Theinitialimpactvelocitylimitwasdeducedbytakingtheprojectilestabilityintoaccountwhenthe cartridgethicknesswasgiven,andtheinfluencesofdifferentprojectile/targetconditionswerediscussed.
