Flattening bvunzo
Machubhu esimbi ane dhayamita rekunze rakakura kupfuura 22 mm uye anosvika 400 mm, uye ukobvu hwemadziro hwakakura kupfuura 10 mm hunofanirwa kuita bvunzo yekubata kumeso. Mushure mokunge sampuli dzakapetwa
Bending test
Machubhu esimbi ane dhayamita rekunze risingapfuuri 22 mm anofanira kupinda muyedzo yekukotama. Kona yekukombama i90o . Radhiyasi yekupeta ndeye 6 nguva yekunze dhayamita yechubhu yesimbi.Mushure mekupeta sampuli, hapana kutsemuka kana kutsemuka kunobvumidzwa kuoneka pamuenzaniso.
Macroscopic kuongorora
