Abstract
TheexplosionprocessesofsphericalPETNchargesinLantiangranitewerenumericallysimulatedbyusingthesoftwareAUTODYN.
ParticlevelocityanddisplacementcurvesatdifferentlocationsinLantiangranitewereobtainedandtheinfluencesofexplosivepropertiesonro
kparticlemovementwerequalitativelyanalyzed.
Thesimulatedparticlevelocityanddisplacementareconsistentwith
theexistentexperimentalresults.Thereliesalargedistinctionbetweenparticlevelocitypeaksfrom
