Elongation=ɛ=(ΔL/L) x 100 Elongation ntawm Break yog ntsuas hauv % (% ntawm elongation vs. thawj qhov loj me thaum tawg tshwm sim). Qhov siab tshaj plaws elongation piv txwv li, thaum so, emax tseem hu ua "strain to failure". Qhov kawg elongation qhov tseem ceeb ntawm ob peb puas feem pua yog ib qho rau elastomers thiab zaj duab xis / ntim polyolefins.
Koj suav li cas feem pua elongation ntawm pob txha?
Percent Elongation - Lub zog ntawm pob txha hauv qhov nro, qhia tias yog percentage=((gage ntev - pib gage ntev) / pib gage ntev) x 100. Qhov feem pua elongation yog ntsuas ntawm ductility.
Dab tsi yog qhov elongation ntawm kev tawg feem pua?
Elongation ntawm so yog qhov feem pua nce ntawm qhov ntev uas cov khoom yuav ua tiav ua ntej tawg. Daim duab no yog qhia raws li feem pua thiab feem ntau yog ntsuas siv txoj kev xeem ASTM D412. Qhov feem pua siab dua feem ntau qhia tau tias cov khoom siv zoo dua thaum ua ke nrog Tensile Strength zoo.
Yuav ua li cas koj xam elongation hauv kev sim tensile?
Elongation=ɛ=(ΔL/L) x 100 Nws yog ntsuas hauv % (% ntawm elongation vs. thawj qhov loj me thaum qhov taw tes tawm los). Elongation ntawm Yield tseem hu ua tensile elongation ntawm yield.
Dab tsi yog elongation ntawm kev tawg hauv roj hmab?
Lub elongation ntawm so yog qhov twg cov khoom siv roj hmab tuaj yeem raug strained (%), ua ntej nws tawg. Peb siv lub zog tensile thiab ncab cov khoom. Ib feem pua ntawm covthawj ntev yog siv los qhia qhov elongation thaum so. Nws yog feem ntau nyob rau hauv qhov kev txiav txim ntawm 100-600%, thiab qee qhov piv txwv txawm mus txog 1000%.
