By using AUTODYN-3D software, the three-dimensional finite element model of the discrete rod warheads has been established. Through Lagrange algorithms, the steel rod and the tungsten carbide rod of the discrete rod warheads with or without filling materials are simulated. It is found that the rod material and the cushioning material have a significant effect on the rod scatters behavior, Loading appropriate buffer materials is in favour of reducing the fly of detonation products and improving the energy utilization ratio of explosives. The theoretical analysis might provide some useful reference for the design of the discrete rod warhead., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=G6+l69ZJkLOsJVDXzxt8Ag==, pdfFileSize=2224708, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
