Rebound　effects　can　be　caused　for　a　blast　door　under　explosion　loadings　of　conventional　weapons.　Such　effects　reaching　a　certain　extent　can　lead　to　severe　reversed　stresses　and　even　destroy　the　hinge　and　lock　system　before　the　door　leaf.　In　this　study,　an　analytical　model　for　the　elastic　rebound　of　a　blast　door　under　explosion　loadings　was　proposed　and　analyzed.　Based　on　the　calculations,　the　effects　of　aspect　ratio　and　load　duration　on　the　rebound　behavior　were　analyzed.　Furthermore,　for　extension　of　the　analysis　from　the　elastic　to　plastic　range,　comparison　of　the　solutions　with　the　analytical　ones　was　made.　The　results　showed　that　the　positive　and　negative　dynamic　shear　force　peaks　of　the　blast　door　deceased　gradually　with　the　aspect　ratio,　whereas　the　rebound　strength　was　inversely　proportional　to　the　load　duration.　For　blast　doors　entering　into　the　plastic　stage,　the　rebound　behavior　was　similar　to　the　elastic　stage,　implying　that　the　design　of　a　blast　door　can　be　based　on　its　characteristics　in　elastic　stage.
