    Abstract
  • Basedonnumericalsimulation,thedynamicresponseofhumanchestencounteringshockin freeblastfieldisinvestigated.CTImagesaretreatedusingthesoftwareofMimics,andthe3-Dmodelofhumanchestisestablished. Accordingtothecharacteristicsofeachbiologictissueinhuman chest,themodelandparametersofthematerialisrightlyselected.Usingfluid-structurecouplingfiniteelementsolverofLS- DYNAsoftware,thedynamicresponseofthelungsunderablastwaveis calculatedandanalyzed.Bythecalculatedpeakoverpressureandpositivephasedurationofincident shockwave,betweenDcandD1injurylevelofthelungsisevaluatedreferringtoBowenscurve.Observingchangesofpressureinsidethelungs, thestressvariationonthelungsurfaceandthemostseverelydamagedareaareobtained. Theshearstressisanalyzed,andpossibilityofdamagecausedby shearstressisunderstood.
