2. Kusanthula kwa magwiridwe antchito a square chubu - kuuma
Kuuma ndi cholozera kuyeza kuuma kwa zinthu zachitsulo. Pakalipano, njira yoyezera kuuma yomwe imagwiritsidwa ntchito kwambiri popanga ndi indentation hardness njira, yomwe imagwiritsa ntchito inndenter yokhala ndi mawonekedwe enaake a geometric kukanikizira pamwamba pa zinthu zachitsulo kuti ziyesedwe pansi pa katundu wina, ndikuzindikira kuuma kwake molingana. ku mlingo wa indentation.
Njira zodziwika bwino zimaphatikizapo Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) ndi Vickers hardness (HV).
3. Kusanthula kwa magwiridwe antchito a square chubu - kutopa
Mphamvu, pulasitiki ndi kuuma zomwe takambirana pamwambapa ndi zizindikiro zonse zamakina azitsulo zomwe zili pansi pa static load. M'malo mwake, zida zambiri zamakina zimagwira ntchito mozungulira, pomwe kutopa kumachitika.
4. Kusanthula kwa magwiridwe antchito a square chubu - kulimba kwamphamvu
Katundu womwe umagwira pamakina pa liwiro lalitali umatchedwa mphamvu yamphamvu, ndipo kuthekera kwachitsulo kukana kuwonongeka kwa katundu kumatchedwa kulimba kwamphamvu.
5. Kusanthula kwa index ya magwiridwe antchitochubu lalikulu- mphamvu
Mphamvu imatanthawuza kuthekera kwa zida zachitsulo kukana kuwonongeka (kupindika kwakukulu kwa pulasitiki kapena kusweka) pansi pa katundu wosasunthika. Popeza njira zogwirira ntchito zimaphatikizira kupsinjika, kupsinjika, kupindika, kukameta ubweya, ndi zina zotero, mphamvuyo imagawidwanso kukhala mphamvu yokhazikika, mphamvu yopondereza, mphamvu yopindika, kumeta ubweya, etc. Nthawi zambiri pamakhala mgwirizano wina pakati pa mphamvu zosiyanasiyana, ndi kulimba kwamphamvu nthawi zambiri kumagwiritsidwa ntchito ngati chizindikiro champhamvu kwambiri.
