Mechanical Properties of Steel

1. Iphuzu lesivuno

Lapho insimbi noma isampula yeluliwe, lapho ukucindezeleka kudlula umkhawulo wokunwebeka, ngisho noma ukucindezeleka kungakhuphuki, insimbi noma isampula iyaqhubeka nokuguquguquka okusobala kwepulasitiki, okubizwa ngokuthi ukuhoxa, kanye nenani elincane lokucindezeleka lapho kwenzeka into evumayo. ingeyephuzu lokukhiqiza.Vumela u-Ps kube amandla angaphandle endaweni yesivuno s, futhi u-Fo abe indawo enqamula ingxenye yesampula, bese iphoyinti lokukhiqiza u-σs = Ps/Fo (MPa)..

2. Amandla esivuno

Iphuzu lokuvuthwa kwezinye izinto zensimbi alibonakali kakhulu futhi kunzima ukulilinganisa.Ngakho-ke, ukuze ulinganise izici zokukhiqiza zezinto ezibonakalayo, ukucindezeleka lapho ukuguqulwa kwepulasitiki okuhlala unomphela kufana nenani elithile (ngokuvamile i-0.2% yobude bokuqala) icacisiwe.amandla anemibandela esivuno noma ukumane unikeze amandla σ0.2.

3. Amandla okuqina

Inani eliphakeme lokucindezeleka elifinyelelwe into ngesikhathi senqubo yokwelula, kusukela ekuqalisweni kuya ekuqhekekeni.Iveza ikhono lensimbi lokumelana nokuphuka.Ngokuhambisana namandla aqinile, kukhona amandla acindezelayo, amandla avumelana nezimo, njll. Vumela i-Pb kube amandla amakhulu okubamba amandla azuzwe ngaphambi kokuthi okubalulekile kukhishwe.

force, i-Fo iyindawo ephambanayo yesampula, bese kuba amandla aqinile σb = Pb/Fo (MPa).

4. Ukwelula

Ngemva kokuba impahla iphukile, iphesenti lobude bayo bepulasitiki bobude ukuya kubude besampula bangempela bubizwa ngokuthi ukwelula noma ukwelula.

5. Isilinganiso samandla esivuno

Isilinganiso sephuzu lesivuno (amandla esivuno) sensimbi kuya kumandla aqinile sibizwa ngokuthi isilinganiso sokuqina kwesivuno.Uma sikhulu isilinganiso sesivuno, siphakamisa ukwethembeka kwezingxenye zesakhiwo.Ngokuvamile, isilinganiso sesivuno se-carbon steel singu-06-0.65, kanti insimbi ephansi ye-alloy structural ingu-065-0.75, kanti i-alloy structural steel yi-0.84-0.86.

6. Ubulukhuni

Ukuqina kukhombisa ikhono lempahla ukumelana nokucindezelwa kwento eqinile ebusweni bayo.Ingenye yezinkomba zokusebenza ezibalulekile zezinto zensimbi.Ngokuvamile, ukuphakama kokuqina, kungcono ukumelana nokugqoka.Izinkomba zokuqina ezivame ukusetshenziswa yiBrinell hardness, Rockwell hardness kanye neVickers hardness.
