Txhua yam khoom ua tau zoo

Kev ua tau zoo ntawm cov khoom siv yog hais txog cov khoom siv ntawm cov khoom thaum siv, nrog rau cov khoom siv dag zog, lub cev thiab tshuaj. Rau feem ntau, cov khoom siv dag zog yog qhov tseem ceeb tshaj lag luam. Cov cwj pwm tsis paub meej txhua yam khoom muaj xws li lub zog tsis muaj zog, elastic txwv σe, yield zog zog lossis σ0.2, elongation δ, seem shrinkage ψ, kev cuam tshuam. Toughness ak thiab hardness HRC los yog HBS. Lub zog ntawm cov ciaj ciam no yog qhov ua tau zoo ntawm kev ua haujlwm ntawm cov khoom siv dag zog. Tsuas yog thaum lub zog ua tau raws li cov kev cai tau tuaj yeem ua rau qhov chaw ua hauj lwm kom zoo thiab ruaj khov. Nyob rau hauv txoj kev tshawb ntawm cov khoom mechanics, nws tau raug pom tias qhov kev ywjpheej tso cai siv los tsim cov txheej txheem phom sij lossis kev ruaj ntseg ntawm ib sab yog xam raws cov ntaub ntawv muaj zog.
