Indlela yokuhlola izakhiwo zemishini ye-graphite enwetshiwe. Ukuhlolwa kwamandla okuqinile kwe-graphite enwetshiwe kufaka phakathi umkhawulo wamandla aqinile, i-tensile elastic modulus kanye nokwelulwa kwempahla yegraphite enwetshiwe. Umhleli olandelayo we-Furuite Graphite wethula indlela yokuhlola izakhiwo zemishini ye-graphite enwetshiwe:
Kunezindlela eziningi zokuhlolwa okuqinile kwezakhiwo zemishini yegraphite enwetshiwe, njengokulinganisa komshini, i-laser speckle, ukuphazamiseka nokunye. Ngemuva kokuhlolwa okuningi nokuhlaziya, kutholakala ukuthi idatha yamandla eqinile ingatholwa kangcono ngokuhlolwa kwe-tensile ye-125 worm graphite. Umkhawulo wamandla e-tensile ubhekisela emthwalweni wamandla amakhulu aqinile isifanekiso esingathwala indawo ngayinye yeyunithi, futhi usayizi waso ungenye yezinkomba ezibalulekile zokulinganisa ngokuphelele izakhiwo zemishini zezinto ezinwetshiwe zegraphite.
Ukuhlolwa okuqinile kwe-elastic modulus kungathola inani elilinganiselwe le-elastic elastic modulus ngokusebenzisa ijika le-stress-strain elitholwe ekuhlolweni okuqinile kwama-graphite anwetshiwe angama-83 kanye nendlela eqinile ye-secant. Idatha yezibalo ye-elongation ingatholwa ngokuhlola ama-graphite anwetshiwe ama-specimens angama-42.
I-graphite eyandisiwe ekhiqizwa i-Furuite graphite inezakhiwo ezinhle kakhulu futhi isetshenziswa kabanzi. Izici zemishini ezisezingeni eliphezulu, ezibizwa nangokuthi izakhiwo zemishini, zifaka amandla okucindezela, i-compressive elastic modulus, ukuqina kanye nesilinganiso sokucindezela ekushiseni okuphezulu isikhathi esithile.
