Ibipimo bya tekiniki by'umusingi wa granite mechanical.

 

Granite, ibuye rikoreshwa cyane mu gusya, rizwiho kuramba no gukomera kwaryo, bigatuma riba ibikoresho byiza byo gukoresha mu gusya imashini mu mishinga itandukanye y'ubwubatsi. Gusobanukirwa ibipimo bya tekiniki by'imashini za granite ni ingenzi ku bahanga mu by'ubwubatsi kugira ngo inyubako zikomeze kuba nziza kandi zirambe.

Kimwe mu bipimo by'ingenzi bya tekiniki bya granite ni imbaraga zayo zo gukanda, ubusanzwe ziri hagati ya 100 na 300 MPa. Ubu bunini bwo gukanda butuma granite ishobora kwihanganira imitwaro ikomeye, bigatuma ikoreshwa mu mashini n'ibikoresho biremereye. Byongeye kandi, granite igaragaza imyenge mike, muri rusange iri hagati ya 0.1% na 0.5%, ibi bikaba bigira uruhare mu kurwanya amazi yinjira no kwangirika kw'imiti, birushaho kunoza ubushobozi bwayo bwo gushingwa imashini.

Indi ngingo y'ingenzi ni uburyo granite ihinduka, aho kuri granite ingana na GPa 50 kugeza kuri 70. Iyi miterere igaragaza uburyo ibikoresho bizahinduka iyo bishyushye, bigatanga ubumenyi ku mikorere yabyo iyo bishyushye cyane. Ingano nto y'ubushyuhe bwa granite, iri hagati ya 5 na 7 x 10^-6 /°C, ituma igumana ubuziranenge bwayo nubwo ubushyuhe buhindagurika, bigatuma iba amahitamo yizewe ku byuma bishingirwaho mu kirere gitandukanye.

Ubucucike bwa granite, ubusanzwe buri hagati ya 2.63 na 2.75 g/cm³, nabwo bugira uruhare runini mu gushushanya urufatiro. Ubucucike bwinshi bugira uruhare mu gutuma urufatiro ruguma neza, bigabanya ibyago byo kwimuka cyangwa guhinduka uko igihe kigenda gihita. Byongeye kandi, ubudahangarwa bwa granite ku gushwanyagurika no kwangirika bituma iba amahitamo meza ku rufatiro ruhura n’urujya n’uruza rw’imodoka cyangwa imbaraga za mekanike.

Mu gusoza, ibipimo bya tekiniki by’ishingiro rya granite, harimo imbaraga zo gukanda, modulus of elasticity, porosity nke, hamwe n’ubucucike bwinshi, bigaragaza akamaro kayo nk’ibikoresho by’ibanze. Binyuze muri izi miterere, abahanga mu by’imashini bashobora gushushanya ishingiro rikomeye kandi rirambye rijyanye n’ibyo inyubako zigezweho zisaba.
