简介：Inthispapertheelasticconstantsofgraphiteatelevatedtemperaturewereexperimentallyinvestigatedbyusingthevirtualfieldsmethod(VFM).Anewmethodwaspresentedforthecharacterizationofmechanicalpropertiesatelevatedtemperature.Thethree-pointbendingtestswereperformedongraphitematerialsbyanuniversaltestingmachineequippedwithheatingfurnace.Basedontheheterogeneousdeformationfieldsmeasuredbythedigitalimagecorrelation(DIC)technique,theelasticconstantswerethenextractedbyusingVFM.Themeasurementresultsoftheelasticconstantsat500℃wereobtained.Theeffectontheexperimentalresultswasalsoanalyzed.Thesuccessfulresultsverifythefeasibilityofusingtheproposedmethodtomeasurethepropertiesofgraphiteathightemperature,andtheproposedmethodisbelievedtohaveagoodpotentialforfurtherapplications.
