1. Plasticity:
Plasticity yog hais txog lub peev xwm ntawm cov khoom siv hlau los tsim cov yas deformation (mus tas li deformation) yam tsis muaj kev puas tsuaj nyob rau hauv load.
2. Hardness:
Hardness yog ib qho kev ntsuas ntawm softness thiab hardness ntawm cov ntaub ntawv hlau. Tam sim no, feem ntau siv txoj kev ntsuas hardness nyob rau hauv ntau lawm yog txoj kev indentation hardness, uas siv ib tug indenter ntawm ib tug tej yam geometric duab los nias rau hauv lub saum npoo ntawm cov khoom hlau raug kuaj nyob rau hauv ib tug tej yam load, thiab hardness tus nqi yog ntsuas. raws li qhov degree ntawm indentation.
3. qaug zog:
Lub zog, plasticity, thiab hardness tau tham ua ntej yog tag nrho cov cim qhia ntawm cov khoom siv hluav taws xob ntawm cov hlau nyob rau hauv cov khoom zoo li qub. Qhov tseeb, ntau lub tshuab ua haujlwm tau ua haujlwm nyob rau hauv kev thauj khoom cyclic, thiab qaug zog yuav tshwm sim hauv cov khoom raws li cov xwm txheej zoo li no.
4. cuam tshuam toughness:
Lub load ua haujlwm ntawm lub tshuab ua haujlwm ntawm kev kub ceev yog hu ua cuam tshuam load, thiab lub peev xwm ntawm cov hlau los tiv thaiv kev puas tsuaj nyob rau hauv kev cuam tshuam load yog hu ua cuam tshuam toughness.
5. Lub zog:
Lub zog yog hais txog lub peev xwm ntawm cov khoom siv hlau los tiv thaiv kev puas tsuaj (cov yas deformation ntau dhau los yog tawg) nyob rau hauv cov khoom zoo li qub. Txij li thaum lub load ua 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, flexural zog, shear zog, thiab lwm yam. Muaj feem ntau muaj kev sib raug zoo ntawm ntau yam zog. Hauv kev siv, lub zog tensile feem ntau yog siv los ua qhov taw qhia lub zog tshaj plaws.
