Abstract

Basedona50-mm-diametersplitHopkinsonpressurebar(SHPB)systemandaself-developedconcrete- likematerialrapidheatingdevice,impactcompressiveexperimentswerecarriedout. Thestress-straincurvesatdifferenttemperatureandthreekindsofimpactvelocitieswereobtained. BasedontheZWTvisco-elasticconstitutivemodelanddamageevolutionofcementmortarfollowing Weibulldistribution,thedamagethermo-viscoelasticconstitutiveequationathighstrainrateswas proposed.Throughthenumericalfitting,theparametersoftheconstitutiveequationwereobtained. Comparisonsshowthatthemodelpredictionsagreewellwiththeexperimentresults.
