Abstract

TheJWLEOSparametersareveryimportantinnumericalsimulationsonexplosives,which canbeaffirmedfromcylinderexperiments.Butinactualcomputations,theseparametersmaydepart fromtheoriginalones.SoaimedtotheJWLEOSparameters,theuncertaintyquantificationwasexplored. ThedistributionofthemainparameterR1 wasgivenwithmathematicalandphysicalanalyses. Andtheuncertaintyquantificationanalysiswascarriedoutforthevelocityattheouterinterfaceofthe copperflyerdrivenbythePBX9404explosive.Theanalysismethodusedinthepaperish
