Abstract

Aone-dimensionalshockmodelandathree-dimensionalcell-basedfiniteelementmodelare developedforthedynamiccrushingofametallicfoamrodstrikingarigidwall.Theshockmodelis proposedbyusingthecontinuum-basedstresswavetheoryandassumingarate-independent,rigidnonlinearhardeningplasticconstitutiverelationofthefoam, thenanimplicitexpressionfordeterminingtherelationbetweenthelocalstrainbehindtheshockfrontandtheimpacttimeisobtained. The cell-basedfiniteelementmodelofaclosed-cellaluminumfoamisconstructedbythethree-dimensional Voronoitechnique,anditsdynamiccrushingprocessissimulatedbyusingtheABAQUS/Explicit code.Theleastsquaresmethodisusedtocalculatethedeformationgradientandlocalstrainfield. Comparingwiththesimulationresults,theshockmodelpresentsgoodpredictionsofthestressand strainbehindtheshockfront.
