1.Imbaraga za Tensile (σb): Imbaraga ntarengwa (Fb) icyitegererezo gihura nimpagarara iyo gikururwa, kigabanijwe na stress (σ) cyakuwe mubice byambere byambukiranya ibice (So) byikigereranyo, byitwa imbaraga zingana ( σb), muri N / mm2 (MPa).Yerekana ubushobozi ntarengwa bwibikoresho byicyuma kugirango birwanye ibyangiritse.Aho: Fb - imbaraga ntarengwa urugero rwihanganira iyo rukwega, N (Newton);Noneho - umwimerere wambukiranya igice cyurugero, mm2.
2.ingingo yumusaruro (σs): ibikoresho byicyuma hamwe numusaruro utanga umusaruro, guhangayika mugihe urugero rushobora gukomeza kuramba nta kongera imbaraga (guma gahoraho) mugihe cyo kurambura, bita umusaruro.Niba imbaraga zigabanutse, ingingo zo hejuru nu munsi zo gutanga umusaruro zigomba gutandukanywa.Igice cy'umusaruro ni N / mm2 (MPa).Umusaruro wo hejuru (σsu): imihangayiko ntarengwa mbere yo gutanga umusaruro n'imbaraga zabanje kugabanuka;Ingingo yo gutanga umusaruro muke (σsl): guhangayikishwa byibura mugice cyo gutanga umusaruro mugihe ingaruka yambere yinzibacyuho itabazwe.Aho: Fs - gutanga imbaraga (guhoraho) yikigereranyo muburemere, N (Newton) Rero - umwimerere wambukiranya igice cyurugero, mm2.
3.Kurambura nyuma yo kuruhuka: (σ) Mu kizamini cya tensile, ijanisha ryo kwiyongera muburebure bwikigereranyo nyuma yo gukuramo igipimo cyacyo kugeza muburebure bwikigereranyo cyambere byitwa kurambura.Byerekanwe muri σ, igice ni%.Aho: L1 - uburebure bwikigereranyo nyuma yikigereranyo gikururwa, mm;L0 - uburebure bwikigereranyo cyumwimerere, mm.
4.Kugabanuka kw'ibice: (ψ) Mu kizamini cya tensile, kugabanuka kwinshi kwagace kambukiranya agace kagabanutse nyuma yikigereranyo kimaze gukururwa nkijanisha ryagace kambere kambukiranya igice bita kugabanuka kwagace.Byerekanwe nka ψ, muri%.Aho: S0 - umwimerere wambukiranya igice cyurugero, mm2;S1 - agace ntarengwa kambukiranya igice kugabanuka nyuma yikigereranyo gikuweho, mm2.
5.Icyerekezo gikomeye: ubushobozi bwibikoresho byicyuma cyo kurwanya indentation yikintu gikomeye hejuru, byitwa gukomera.Ukurikije uburyo bwikizamini hamwe nubunini bwakoreshejwe, gukomera birashobora kugabanywa gukomera kwa Brinell, gukomera kwa Rockwell, gukomera kwa Vickers, gukomera kwa Shore, microhardness hamwe nubushyuhe bukabije.Kuri tube ikoreshwa muri Brinell, Rockwell, Vickers gukomera kwa gatatu.
Gukomera kwa Brinell (HB): Ukoresheje umupira wicyuma cyangwa karbide yumurambararo runaka, kanda imbaraga zipimishije (F) hejuru yikigereranyo, ukureho imbaraga zipimisha nyuma yigihe cyagenwe, hanyuma upime diameter ya indentation (L) hejuru yikigereranyo.Agaciro gakomeye ka Brinell nigipimo cyabonetse mugabanye imbaraga zipimisha nubuso bwubuso bwa indentation.Byerekanwe nka HBS (umupira wibyuma) muri N / mm2 (MPa).
Imiyoboro y'ibyuma bishyushye ikoreshwa cyane mu bwubatsi, imashini, ubucukuzi bw'amakara, inganda z’imiti, amashanyarazi, imodoka za gari ya moshi, inganda z’imodoka, umuhanda munini, ibiraro, kontineri, ibikoresho bya siporo, imashini z’ubuhinzi, imashini zikomoka kuri peteroli, imashini zishakisha n’izindi nganda zikora inganda .
Umuyoboro w'icyuma wa galvanised ni umuyoboro w'icyuma usudira ufite ubushyuhe cyangwa amashanyarazi ya elegitoronike.Galvanisation irashobora kongera imbaraga zo kwangirika kwimiyoboro yicyuma kandi ikongerera igihe cyumurimo.Umuyoboro w'icyuma wa Galvanised ufite uburyo butandukanye bwo gukoresha, usibye gukoreshwa nk'umuyoboro w'amazi rusange y’umuvuduko ukabije nk'amazi, gaze na peteroli, akoreshwa kandi nk'umuyoboro w'amavuta hamwe n'umuyoboro wa peteroli mu nganda za peteroli, cyane cyane muri imirima ya peteroli yo mu nyanja, nk'icyuma gishyushya amavuta, gukonjesha hamwe no gutobora amakara hamwe no guhanagura amavuta kubikoresho bya kokiya ya chimique, kandi nk'umuyoboro wo gushyigikira ibirundo bya trestle hamwe n'ibyobo bicukurwamo amabuye y'agaciro, n'ibindi.
Umuyoboro wamazi, umuyoboro wamavuta, umuyoboro wa scafolding, uruzitiro rwumuhanda, igipfukisho, nibindi.
