1. Performance Index Analysis ntawm Square Tube - Plasticity
Plasticity yog hais txog lub peev xwm ntawm cov khoom siv hlau los tsim cov yas deformation (mus tas li deformation) nyob rau hauv kev thauj khoom yam tsis ua haujlwm.
2. Performance Index Analysis ntawm Square Tube - Hardness
Hardness yog ib qho kev ntsuas ntawm softness thiab hardness ntawm cov ntaub ntawv hlau. Txoj kev siv feem ntau los ntsuas qhov hardness hauv kev tsim khoom yog txoj kev indentation hardness, uas siv ib qho indenter ntawm ib qho duab geometric rau indent rau hauv qhov chaw ntawm cov khoom hlau yuav tsum tau kuaj nyob rau hauv ib tug tej yam load, thiab txiav txim nws hardness tus nqi raws li cov degree ntawm indentation.
Cov kev siv feem ntau suav nrog Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) thiab Vickers hardness (HV).
3. Performance Index Analysis ntawm Square Tubes - qaug zog
Lub zog, plasticity, thiab hardness tau tham saum toj no yog tag nrho cov cim qhia ntawm cov khoom siv hluav taws xob ntawm cov hlau hauv qab cov khoom zoo li qub. Qhov tseeb, ntau lub tshuab ua haujlwm tau ua haujlwm nyob rau hauv kev thauj khoom cyclic, nyob rau hauv cov xwm txheej uas ib feem tuaj yeem ua rau qaug zog.
4. Performance Index Analysis ntawm Square Tube - Impact Toughness
Lub load ua haujlwm ntawm lub tshuab ntawm kev kub ceev yog hu ua kev cuam tshuam load, thiab lub peev xwm ntawm cov hlau los tiv thaiv kev puas tsuaj nyob rau hauv qhov cuam tshuam load yog hu ua qhov cuam tshuam toughness.
5. Performance Index Analysis ntawm Square Tube - Lub zog
Lub zog yog hais txog kev ua haujlwm ntawm cov khoom siv hlau tsis ua haujlwm (cov yas deformation ntau dhau los yog tawg) nyob rau hauv cov khoom zoo li qub. Txij li thaum qhov kev txiav txim ntawm lub load yog nyob rau hauv daim ntawv ntawm nro, compression, dabtsi yog khoov, shearing, thiab lwm yam., lub zog kuj muab faib ua tensile zog, compressive zog, dabtsi yog khoov zog, shear zog, thiab lwm yam. lub zog, thiab lub zog tensile feem ntau yog siv los ua qhov taw qhia lub zog tshaj plaws.
