Indlela yokuvavanya iimpawu zoomatshini zegrafiti eyandisiweyo. Uvavanyo lwamandla okutsalwa kwegrafiti eyandisiweyo luquka umda wamandla okutsalwa, imodulus ye-tensile elastic kunye nokwandiswa kwezinto zegrafiti eyandisiweyo. Lo mhleli ulandelayo weFuruite Graphite uzisa indlela yokuvavanya iimpawu zoomatshini zegrafiti eyandisiweyo:
Kukho iindlela ezininzi zokuvavanya ukutsalwa kweempawu zoomatshini zegrafiti eyandisiweyo, njengokulinganisa ngoomatshini, i-laser speckle, ukuphazamiseka njalo njalo. Emva kovavanyo oluninzi kunye nohlalutyo, kufunyaniswe ukuba idatha yamandla okutsalwa ingafumaneka ngcono ngovavanyo lokutsalwa kwegrafiti ye-worm eyi-125. Umda wamandla okutsalwa ubhekisa kumthwalo wamandla amakhulu okutsalwa anokuthwalwa yisampuli kwindawo nganye, kwaye ubukhulu bayo yenye yezona zikhokelo zibalulekileyo zokulinganisa ngokupheleleyo iimpawu zoomatshini zezinto zegrafiti eyandisiweyo.
Uvavanyo lwe-tensile elastic modulus lunokufumana ixabiso eliqikelelweyo le-tensile elastic modulus ngokusebenzisa i-stress-strain curve efunyenwe kuvavanyo lwe-tensile lweesampuli ze-graphite ezandisiweyo ezingama-83 kunye nendlela ye-rigid secant. Idatha yezibalo yokwandiswa ingafunyanwa ngokuvavanya iisampuli ze-graphite ezandisiweyo ezingama-42.
I-grafiti eyandisiweyo eveliswa yi-graphite ye-Furuite ineempawu ezintle kakhulu kwaye isetyenziswa kakhulu. Iimpawu zoomatshini ezinobushushu obuphezulu, ezikwabizwa ngokuba ziimpawu zoomatshini, ziquka amandla okuxinzelela, i-compressive elastic modulus, ukuqina kunye nomlinganiselo wokuxinzelela kubushushu obuphezulu kangangexesha elithile.
