Abstract

Toexplorethedynamicmechanicalcharacteristicsofice,uniaxialcompressiontestswere carriedoutinthestrainraterangefrom500to2000s-1 byusingthesplitHopkinsonpressurebar (SHPB)techniqueat-25and-10 ℃,respectively.Moldsweredesignedtomanufactureicesamples, andacoolingchamberwasdevelopedtomeetthelow-temperaturecondition.Pulseshaperswere usedtoachieveconstantstrainrateloading.Experimentalresultsshowthatthedynamicstress-strain relationoficeisnonlinear,thepeakstressandfailurestrainincreasewiththeincreaseofstrainrates, andthecompressivestrengthoficedecreaseswiththeincreaseofthetesttemperature.
