Txhais ntawm yield zog
Yield zog yog hais txog qhov tseem ceeb uas cov khoom pib tsim cov yas deformation thaum raug rau sab nraud quab yuam, thiab yog lub peev xwm ntawm cov khoom los tiv thaiv deformation. Rau cov kav dej steel kav, qhov kev twv ua ntej ntawm cov khoom muaj zog yog qhov tseem ceeb rau kev tsim thiab xaiv cov khoom siv hauv cov kav dej.
Yield zog kwv yees txoj kev
Muaj ntau txoj hauv kev rau kev kwv yees lub zog tawm los, thiab cov kev siv feem ntau suav nrog kev suav theoretical thiab kev sim ntsuas.
Theoretical xam txoj kev
Txoj kev suav theoretical yog los twv seb lub cev ntawm cov khoom siv los ntawm cov qauv lej thiab cov qauv ntawm cov qauv. Rau cov kav dej steel kav, feem ntau siv theoretical laij lej txoj kev suav nrog elastic mechanics theory, yas mechanics theory thiab finite element analysis.
Kev sim txoj kev sim
Txoj kev sim kev sim yog kom tau txais cov ntaub ntawv khoom siv hluav taws xob ntawm cov khoom siv los ntawm kev sim thiab ntsuas qhov tseeb. Rau cov kav dej steel kav, feem ntau siv cov kev sim sim muaj xws li tensile test, impact test thiab hardness test.
Cov yam ntxwv cuam tshuam rau lub zog tawm los
Kev twv ua ntej ntawm cov khoom muaj zog yog cuam tshuam los ntawm ntau yam, nrog rau cov tshuaj muaj pes tsawg leeg ntawm cov khoom, txheej txheem kev kho cua sov thiab microstructure. Kev sib txawv ntawm qhov sib txawv ntawm cov yam ntxwv no yuav ua rau muaj qhov sib txawv ntawm qhov muaj zog tawm los.
Kev siv lub zog tawm los
Yield zog tsis yog tsuas yog ib tug theoretical qhia, tab sis kuj lug siv nyob rau hauv tsim thiab xaiv cov khoom ntawm pipeline engineering. Thaum tsim lub raj xa dej, nws yuav tsum xaiv cov khoom tsim nyog raws li qhov kev kwv yees tawm los ntawm lub zog los xyuas kom meej tias cov kav dej muaj lub zog txaus thiab kev nyab xeeb thaum ua haujlwm.
