摘要：

In　order　to　research　the　fracture　behavior,　the　numerical　simulation　of　dynamic　fracture　of　cylindrical　shell　under　lateral　explosion　impulsion　was　successfully　realized　with　arbitrary　Lagrangian-Eulerian　method.　The　result　is　that　explosive　mass　is　incremental　linear　relation　to　wall　thickness　of　shell,　and　the　slope　coefficient　is　changed　by　different　wall　thickness.　With　the　same　condition,　the　element　maximum　stress　increase　showly　to　more　wall　thickness　when　explosive　mass　is　increased.
