摘要：

The　metal　structure　damage　under　explosion　of　detonator　is　simulated　by　LS-DYNA.　The　material　model　applied　is　analyzed　in　detail.　The　difference　between　Euler　and　Lagrange　algorithm　is　described.　The　influences　of　different　meshing　density　on　the　precision　of　results　are　compared.　In　the　plain　strain　problems,　both　two-dimensional　and　three-dimensional　models　are　applicable,　and　their　calculation　results　are　compared.　The　comparison　with　the　experimental　results　shows　that　the　LS-DYNA　can　simulate　the　impact　reaction　of　metal　structure　under　explosion　load　effectively.
