1. Isesengura ryerekana imikorere yumuyoboro wihariye wihariye - plastike
Plastike bivuga ubushobozi bwibikoresho byibyuma kubyara plastike (deformasiyo ihoraho) nta byangiritse munsi yumutwaro.
2. Isesengura ryerekana imikorere yumuyoboro udasanzwe wibyuma - gukomera
Gukomera nigitekerezo cyo gupima ubukana bwibikoresho byicyuma.Uburyo bukoreshwa cyane mugupima ubukana mubikorwa nuburyo bwo kwerekana indentation, aribwo gukoresha indenter hamwe na geometrie runaka kugirango ukande hejuru yibikoresho byapimwe munsi yumutwaro runaka, hanyuma umenye agaciro kayo ukurikije impamyabumenyi ya indentation.
Uburyo bukunze gukoreshwa burimo ubukana bwa Brinell (HB), ubukana bwa Rockwell (HRA, HRB, HRC) na Vickers gukomera (HV).
3. Isesengura ryerekana imikorere yumuyoboro udasanzwe wibyuma - umunaniro
Imbaraga, plastike hamwe nubukomezi byavuzwe haruguru byose byerekana ibimenyetso byubukorikori bwibyuma munsi yumutwaro uhagaze.Mubyukuri, ibice byinshi byimashini bikora munsi yumuzingi, kandi muribi bihe, umunaniro uzaba.
4. Isesengura ryerekana imikorere yumuyoboro wihariye wibyuma - gukomera
Umutwaro ukora kuri mashini kumuvuduko mwinshi byitwa umutwaro wingaruka, kandi ubushobozi bwicyuma bwo kurwanya ibyangiritse munsi yumutwaro byitwa ingaruka zikomeye.
5. Isesengura ryerekana imikorere yumuringa wihariye - imbaraga
Imbaraga bivuga kurwanya ibikoresho byibyuma kunanirwa (guhindagurika gukabije kwa plastike cyangwa kuvunika) munsi yumutwaro uhagaze.Kubera ko ibikorwa byuburyo bwimitwaro birimo impagarara, kwikuramo, kunama no kogosha, imbaraga nazo zigabanijwemo imbaraga zingana, imbaraga zo kwikanyiza, imbaraga zunama n'imbaraga zo gukata.Hariho isano ihuza imbaraga zitandukanye.Mubisanzwe, imbaraga zingana nicyo kintu cyibanze cyerekana imbaraga mukoresha.
