Lub tensile lub zog ntawm aluminium yog ntau dua li lub zog tawm los.
Lub zog tawm los sib raug rau qhov taw tes tawm los. Qhov taw tes tawm los yog hais txog qhov chaw uas cov hlau ua rau cov yas deformation, thiab lub zog sib thooj ua lub zog tawm los. Lub zog tensile yog hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv sab nraud, feem ntau lub zog uas nws tawg hauv kev sim tensile.
tensile zog:
Thaum cov khoom siv aluminium yog yielded mus rau ib theem, vim qhov rearrangement ntawm lub sab hauv siv lead ua nplej, nws tsis kam mus deformation yog zoo dua. Nyob rau lub sijhawm no, txawm hais tias qhov deformation loj hlob sai, nws tsuas tuaj yeem nce nrog qhov nce ntawm kev ntxhov siab kom txog thaum qhov kev ntxhov siab nce mus txog qhov siab tshaj plaws.
Tom qab ntawd, lub peev xwm ntawm covaluminiumcov khoom siv los tiv thaiv deformation yog txo qis, thiab cov yas loj deformation tshwm sim ntawm qhov tsis muaj zog tshaj plaws, qhov chaw hla ntawm cov qauv shrinks sai, thiab qhov tshwm sim ntawm caj dab tshwm sim kom txog thaum nws tawg. Tus nqi siab tshaj plaws (raws li taw tes b) ua ntej cov khoom siv txhuas raug rau tensile tawg yog hu ua lub zog txwv lossis lub zog tensile.
Yield zog:
Thaum qhov kev ntxhov siab tshaj qhov txwv elastic, qhov deformation nce sai. Lub sijhawm no, ntxiv rau elastic deformation, qee cov yas deformation tshwm sim. Thaum qhov kev ntxhov siab mus txog qhov point B, cov yas strain nce sharply, thiab ib tug me me toj siab fluctuates nyob rau hauv lub nkhaus, uas yog hu ua yielding.
Qhov siab tshaj plaws thiab yam tsawg kawg nkaus kev ntxhov siab nyob rau theem no yog hu ua Upper yield point thiab low yield point, ntsig txog. Txij li thaum tus nqi ntawm qhov qis yield point yog qhov ruaj khov, nws yog siv los ua qhov taw qhia ntawm cov khoom siv, hu ua yield point lossis yield zog.
