Abstract

Afunctionallylayeredhoneycombmodelisproposedtocontrolthedynamicenergyabsorptionofferedbyuniformhoneycombs. Thein-planedynamicresponsesarecontrolledbythevariation ofthecellradius.Thenumericalresultsshowthatthroughtheproperchoiceofthegradientcoefficient, theinitialforcepeakcanbereducedsignificantly,andtheenergyabsorptioncanbecontrolled. Moreover,thevaluesforthetransmittedstressesintotheprotectedstructurescanbegreatlyreduced. Thesefindingscanprovidevaluablesuggestionsinthemulti-objectiveoptimaldesignofhoneycombs.
