Abstract

Two-dimensionalnumericalsimulationofdetonationwaveinterferenceamongperforating bulletswasmadebyemployingtheexplicitdynamicfiniteelementprogram.Effectsoftheprojectile bodyondetonationwaveinterferenceamongperforatingbulletswereconsidered.Andtheresultsof numericalsimulationwerediscussed.Themaincauseofinterferenceamongcharges,whichaffected perforationresultinhighshotdensityperforatingtechnology,wastheinterferedpressurefieldof blastwaveanddamageddetonationwave,whichwasdesignedinitially.Theresultsofnumericalsimulationareinagreementwithpreviousphysicalphenomenaandlaws. Thestudyindicatesthatthecalculationmodelandsimulationmethodarereasonableandfeasible, whichcanbeappliedtotheoptimizingdesignforgun- perforatorofhighshotdensity.
