Abstract

Thedynamicmechanicalpropertiesofhexagonalaluminum honeycombswithvariouscell configurationsarestudiedbyemployingtheexplicitdynamicnumericalsimulations.Thedeformation modeandthecrushingstrengthofthehoneycombs,aswellastheinfluencefactorsarediscussed. Fivekindsofcellconfigurationsareacquiredbychangingthecell-wallangle,andthreelevelsofimpactvelocityareinvolvedinthenumericalsimulations. Theresultsshowthatunderthequasi-static deformationmode,thecrushingstrengthofthehoneycombsisdominatedbythecellconfiguration. Oncethehoneycombsdeformationturnsintothedynamicmode,theinertiaeffectisnotableandbecomesthedecidingfactorofthehoneycombscrushingstrength, whiletheinfluenceofthecellconfigurationisinconspicuous. Underthetransitionalmode,thecrushingstrengthofthehoneycombsisdeterminedbyboththeinertiaeffectandthecellconfigurationsimultaneously. Moreover,thehigher theimpactvelocity,themoresignificanttheproportioninertiaeffect.
