Cov cuab yeej siv tshuab kuj tseem siv los pab faib thiab txheeb xyuas cov khoom siv. Cov khoom siv feem ntau suav tias yog lub zog, ductility, tawv , cuam tshuam tsis kam, thiab tawg toughness. Cov khoom siv feem ntau yog anisotropic, uas txhais tau hais tias lawv cov khoom siv sib txawv nrog kev taw qhia.

Tom qab ntawd, cov khoom siv tshuab yog dab tsi?

Txhais. Mechanical zog yog lub cev khoom tias ib yam khoom nthuav tawm thaum siv lub zog. Piv txwv ntawm mechanical zog yog cov modulus ntawm elasticity, tensile zog , elongation, hardness thiab qaug zog txwv.

Tsis tas li ntawd, dab tsi yog lub cev thiab cov khoom siv kho tshuab? Lub cev muaj zog yog tej yam uas ntsuas tau. Cov no yog tej yam xws li ceev, melting point, conductivity, coefficient ntawm expansion, thiab lwm yam. Mechanical zog yog cov hlau ua li cas thaum sib txawv zog siv rau lawv. Qhov ntawd suav nrog tej yam xws li zog , ductility, hnav tsis kam, thiab lwm yam.

Hauv qhov no, cov cuab yeej cuab yeej cuab tam yog dab tsi?

Txhais. Nyob rau hauv mechanics ntawm cov ntaub ntawv, lub zog ntawm a khoom Nws muaj peev xwm tiv taus ib qho kev thov tsis ua haujlwm lossis cov yas deformation. Teb ntawm zog ntawm cov ntaub ntawv cuam tshuam nrog lub zog thiab deformations uas tshwm sim los ntawm lawv cov kev ua ntawm a khoom.

Cov khoom sib txawv ntawm cov khoom yog dab tsi?

Lub cev khoom xa mus rau khoom uas tuaj yeem pom lossis ntsuas yam tsis tau hloov pauv qhov muaj pes tsawg leeg khoom . Piv txwv xws li xim, hardness thiab tsis hnov tsw thiab khov, melting thiab boiling ntsiab lus. Tshuaj khoom raug tshawb pom los ntawm kev soj ntsuam cov tshuaj tiv thaiv.
