1. Tanga ingingo
Iyo ibyuma cyangwa icyitegererezo kirambuye, mugihe imihangayiko irenze urugero rwa elastique, nubwo imihangayiko itiyongera, ibyuma cyangwa icyitegererezo bikomeza guhinduka muburyo bugaragara bwa plastike, byitwa gutanga umusaruro, hamwe nagaciro gake cyane mugihe cyo gutanga umusaruro kibaye ni ku musaruro.Reka Ps ibe imbaraga ziva hanze yumusaruro s, na Fo ibe agace kambukiranya icyitegererezo, hanyuma ingingo yumusaruro σs = Ps / Fo (MPa)..
2. Tanga imbaraga
Umusaruro wibikoresho bimwe byicyuma ntibigaragara cyane kandi biragoye kubipima.Kubwibyo, kugirango bapime ibiranga umusaruro wibintu, guhangayika mugihe ihindagurika rya plastike rihoraho risigaye rihwanye nagaciro runaka (mubisanzwe 0.2% yuburebure bwumwimerere).ni imbaraga zitanga umusaruro cyangwa gutanga gusa imbaraga σ0.2.
3. Imbaraga zikomeye
Agaciro ntarengwa gashobora kugerwaho nibikoresho mugihe cyo kurambura, kuva gutangira kugeza kuvunika.Irerekana ubushobozi bwibyuma byo kurwanya kumeneka.Bihuye nimbaraga zingutu, hariho imbaraga zo kwikuramo, imbaraga zidasanzwe, nibindi reka reka Pb ibe imbaraga ntarengwa zagerwaho mbere yuko ibikoresho bikururwa
imbaraga, Fo nigice cyambukiranya igice cyicyitegererezo, hanyuma imbaraga zingana σb = Pb / Fo (MPa).
4. Kurambura
Ibikoresho bimaze kumeneka, ijanisha ryuburebure bwa plastike yuburebure bwa sample yambere byitwa kwagura cyangwa kuramba.
5. Tanga imbaraga zingana
Ikigereranyo cyumusaruro (imbaraga zumusaruro) wibyuma nimbaraga zingana byitwa umusaruro-imbaraga.Ninini igereranyo cyumusaruro, niko kwizerwa kwibice byubatswe.Mubisanzwe, igipimo cyumusaruro wibyuma bya karubone ni 06-0.65, naho ibyuma byubatswe buke buke ni 065-0.75, naho ibyuma byubatswe ni 0.84-0.86.
6. Gukomera
Gukomera byerekana ubushobozi bwibikoresho byo kurwanya gukanda ikintu gikomeye hejuru yacyo.Nimwe mubintu byingenzi byerekana imikorere yibikoresho byicyuma.Mubisanzwe, uko gukomera gukomera, niko kwihanganira kwambara.Ibipimo bikoreshwa cyane ni ubukana bwa Brinell, ubukana bwa Rockwell hamwe na Vickers gukomera.
