Imiterere yubukorikori bwibyuma bivuga ibiranga ibyuma munsi yimbaraga zo hanze, cyane cyane harimo ibipimo bikurikira.
Imbaraga Zihebujeσb: ingingo ntarengwa yibibazo kuri tensile stress-strain curve, unit
Ni MPa.
Lim Gutanga Imipakaσs: iyo guhangayikishwa cyane nibintu birenze urugero rwa elastique kandi guhindura plastike bitangiye kugaragara Stress.Nta musaruro ugaragara wibiboneka mumurongo uhangayikishije-umurongo wibikoresho bimwe, ni ukuvuga ko umusaruro wacyo udashobora kugenwa neza Ingingo.Muri iki kibazo, harasobanuwe mubuhanga ko agaciro ka stress ya 0.2% ihindagurika ryibisigisigi byafashwe nkurugero ntarengwa rwo gutanga umusaruroσ0.2 bigaragarira muri MPa.
Lim Imipaka yo kwihangana: kuvunika kwicyitegererezo nyuma yigihe runaka kubushyuhe runaka
Impuzandengo yikigereranyo.Muri injeniyeri, mubisanzwe bigaragazwa nimpuzandengo yibiciro byintangarugero mugihe ivunitse kuri 105h ku gishushanyo mbonera cya bito ni MPa.
Lim Imipaka ntarengwa: kora icyitegererezo gitanga urugero runaka Agaciro ka stress.Imbonerahamwe yibiciro byibyuma kubushyuhe bwa 105h na creep igipimo cya 1% mubisanzwe bikoreshwa mubuhanga Ni muri MPa.
Kurambura Ijanishaδ8: yerekana ko mugihe icyitegererezo cyangiritse mugupimisha tensile Ijanisha ryo kurambura plastike.Nibipimo byo gupima plastike yicyuma.Uburebure bwumwimerere bwicyitegererezo bwatoranijwe muri rusange nkuburebure bugororotse bwicyitegererezo
Inshuro 5 cyangwa inshuro 10 diameter, icyitegererezo rero gifite δ5na δ10, muri%.
Kugabanya Agaceψ: yerekana ko mugihe icyitegererezo cyangiritse mugupimisha tensile
Igipimo cyimiterere ya plastike.Nibindi bipimo byo gupima plastike yibikoresho, bigaragarira muri%.
⑦ Ingaruka Agaciro A.k: Ni igipimo cyo gukomera kwicyuma kandi kigena niba ibyuma bifite kunanirwa gukabije Icyerekezo, igice: J.
⑧ Gukomera: byerekana ukurwanya ibintu kwihindagurika rya plastike yaho hamwe no kwambara kwambaye.Hano hari ubwoko butatu bwimbonerahamwe Yerekana uburyo, ni ukuvuga ubukana bwa Brinell HB, Rockwell gukomera HR na Vickers Vickers Diamond Hardness HV ifite uburyo butandukanye bwo gupima nuburyo bukoreshwa.Ukurikije ubunararibonye Hariho isano igereranijwe hagati yubukomezi nimbaraga zikomeye kuburyo bukurikira: kuzunguruka no mubisanzwe ibyuma bya karuboneσb= 0.36HB;Kuzunguruka no bisanzwe bisanzwe bya karubone Icyuma cyangwa ibyuma bito bitoσb= 0.35HB;Ubukomere ni 250 ～ 400HB, hamwe nicyuma gikoreshwa nubushyuheσb= 0.33HB.
Bitewe nuburyo bworoshye bwo gupima, ubukana bwa zone yibasiwe nubushyuhe nabwo bukunze gukoreshwa kugirango hamenyekane urugero rwo gukomera kwingingo zasuditswe.
