Lub zog tensile kawg (UTS) yog cov khoom siv siab tshaj plaws rau kev tawg. Nws yog sib npaug rau qhov siab tshaj plaws load uas tuaj yeem nqa tau los ntawm ib square inch ntawm qhov chaw hla ntu thaum lub load yog thov raws li qhov yooj yim nro. UTS yog qhov siab tshaj plaws engineering stress nyob rau hauv ib tug uniaxial stress-strain test.
UTS yog dab tsi?
The SI unit of UTS yog Pascal lossis Pa. Nws feem ntau yog qhia hauv megaPascals, yog li tus UTS feem ntau qhia hauv megaPascals (los yog MPa). Hauv Teb Chaws Asmeskas, qhov UTS feem ntau qhia hauv phaus ib square inch (los yog psi).
Puas tensile zog sib npaug rau qhov kawg lub zog?
Tensile lub zog feem ntau hu ua qhov kawg tensile lub zog thiab ntsuas nyob rau hauv units ntawm quab yuam ib cheeb tsam cross-sectional. … Qhov kawg lub zog (B) - Qhov siab tshaj plaws kev nyuaj siabcov khoom siv tau.
Qhov txawv ntawm qhov kawg tensile lub zog thiab lub zog tawm los yog dab tsi?
Yield zog yog siv rau hauv cov ntaub ntawv uas nthuav tawm tus cwj pwm elastic. Nws yog qhov siab tshaj plaws tensile kev nyuaj siab cov khoom siv tau ua ntej deformation mus tas li. Lub zog kawg yog hais txog qhov kev ntxhov siab ntau tshaj ua ntej ua tsis tiav.
Dab tsi yog lub zog tensile nrog piv txwv?
Lub zog tensile yog qhov ntsuas ntawm lub zog uas yuav tsum tau rub qee yam xws li hlua, xaim, lossis kab teeb pom kev zoo mus rau qhov chaw uas nws tawg. Lub zog tensile ntawm cov khoom yog qhov siab tshaj plaws ntawm tensile stressuas nws tuaj yeem siv ua ntej ua tsis tiav, piv txwv li tawg.
