Binyuze mu kwigana imyenda ikora ku ntoki nko gukurura, gukanda, gukomeretsa, gukata no gukanda, ubunini bwigitambara, kunama, kwikomeretsa, guterana hamwe n’imiterere ya tensile birageragezwa, kandi ibipimo bitanu byerekana ubunini, ubworoherane, gukomera, kworoha no gukomera biboneka kugirango dusuzume neza uburyo bwuzuye bwimyumvire yimyenda. Bikwiranye nibicuruzwa rusange bya fibre flake: umwenda wimyenda, imyenda yo murugo, imyenda idoda, ubudodo, imbere yimodoka, uruhu, impapuro, nibindi.
Ihame ry'ikizamini cyo gukoraho imyenda:
Igereranya ibyiyumvo byimyumvire yukuboko kwabantu kumyenda. Indenters zose zikoreshwa ni ishusho ya silindrike yigana intoki zabantu nimirongo myiza, ikoreshwa mukwigana urutoki. Indenter nayo ifata ishusho yimwe hejuru na ebyiri hepfo kugirango bigane inzira yo gukoraho abantu. Sisitemu igereranya ibipimo bihuye binyuze mugupima ibintu bifatika, nko guhonyora, kunama, guterana no guhagarika umutima, kandi ikabona ubunini bwo kwikuramo hejuru, ubworoherane SF, gukomera ST, ubworoherane SM no gukomera LT, hanyuma igasuzuma uburyo bwuzuye bwa umwenda.
1. Indangantego yubugari, ubunini bwimyenda igabanijwe nubuso bugoramye.
2. Mu cyiciro cya mbere, ubuso burahagarikwa kugirango haboneke compression modulus na compression deformasiyo, bigaragazwa nkubwitonzi SF.
3. Mu cyiciro cya kabiri, ikizamini cyo kugunama kibona kugunama ntarengwa, kugorora modulus, kugoreka akazi, nibindi, bigaragazwa nkugukomera ST.
4. Mu cyiciro cya gatatu, impuzandengo yo guteranya imbaraga, coefficient de fraisse, umurimo wo guterana, nibindi, hamwe na dogere yo kunyerera SM iboneka mugupimisha.
5.Mu cyiciro ⅳ, modulus ya tensile, akazi katoroshye, nibindi biboneka mugupimisha tensile, bigaragazwa nkuburemere LT. Isuzuma ryuzuye ryibisubizo byikizamini: uburyo bwuzuye CH = A * SF + B * ST + C * SM + D * LT sisitemu izabona SF, ST, SM, LT buri cyegeranyo kigabanijwemo urwego rumwe, ebyiri, eshatu, enye, eshanu . Imiterere yuzuye ni igiteranyo cyuburemere bwubworoherane, gukomera, koroha no gukomera, hamwe na coefficient A, B, C na D bigenwa neza ukurikije imikoreshereze, ubwoko nibikoresho.
Ibiranga ibicuruzwa:
1. Kwigana amashusho yintoki zabantu
2. Kugereranya ibipimo bizatuma ibisubizo birushaho kuba siyansi
3, imikorere yoroshye, imashini imwe gupima ibipimo byinshi
4. Guhuza imiterere yubukanishi hamwe nikizamini cyumubiri
5, ibikoresho birahenze cyane, ibikoresho byumwimerere bisobanutse neza, kugenzura neza, gukora neza
