Abstract

Along-rodprojectilepenetratinglayeredmetaltargetswasnumericalsimulatedbyusing AutodynprogrambasedonthemeshfreeSPH method.Theresidualvelocityandkineticenergyafter theprojectilepenetratingintothefirsttargetwereanalyzed,andthefragmentswereobtained.The effectofdifferentinitialvelocityormassonpenetrationwasdiscussed.Thesimulatedresultswere comparedwiththeexperimentalones.Itisshownthatthesimulatedresultsarereasonableandthey canexactlyreflectthepenetrationprocessofalong-rodprojectileintoalayedtarget.
