Toexplorethesplittingstrengthofexpandedpolystyrene(EPS)concretewiththedifferent volumeconcentrationsofEPS,Braziliandiscspecimenswerediametrallyimpactedbyusinga74-mmdiametersplitHopkinsonpressurebar( SHPB)atdifferentimpactvelocities.ForeachvolumeconcentrationofEPS, theBraziliandiscspecimensweretestedinthecasesoftwodifferentparticlesizes ofEPS,respectively.Andaccuratelydesignedcushionswereplacedintheinterspacesbetweentheinputandoutputbarsandthespecimenstopreventthespecimensfrombei gcrushedduetothestress concentrationatthetwoendsofthespecimens.Atthesametime,anappropriatepulseshaperwas usedtoensureenoughtimeforthespecimenstoreachanequilibriumstressstateduringtheexperiment.
