    Abstract
  • Tounderstandandimprovethecrashworthinessofflexiblecontainers,thedynamicbehaviorsofthecontainerunderimpactloadingwerenumericallysimulated. ThewatermovementandsloshinginthecontainerweremodeledbyusingtheALEmethod. Theinteractionbetweenthecontainer andfluidwasstudiedbyapplyingthepenaltymethod.Themodelandapproacheswerevalidatedby comparingnumericalresultswithexperimentaldata.Basedontheaboveinvestigation,numericalsimulationwasperformedtoexploretheinfluencesofdropheightandwaterquantityonthedynamicresponseofthecontainer. Andthedeformationandstressdistributionatthekeypositionswereanalyzed. Resultsdisplaythattheshoulderofthecontaineristhemostvulnerablepartduringimpact; thatbothdropheightandwaterquantityhavegreateffectsonthecrashworthinessofthecontainer; thatthemaximumdynamicstressofthecontainerisproportionaltodropheightandthereliesaVshapedrelationbetweenthemaximumdynamicstressa dwaterquantity.
