Kev ua tau zoo ntawm Kev Ntsuas Cov Tshuab

Chav ntsuas kub tensile kuaj cov khoom siv hlau
Cov khoom siv xws li: cov khoom siv hlau thiab cov khoom tsis yog xim hlau. Lub peev xwm ntawm cov khoom siv los tiv thaiv deformation los yog kev puas tsuaj nyob rau hauv cov quab yuam sab nraud yog hu ua lub zog ntawm cov khoom siv.
Kev ua tau zoo muaj xws li: lub zog, plasticity, elasticity, brittleness, toughness, tawg toughness, hardness, thiab lwm yam.
Lub zog: Lub peev xwm ntawm cov khoom siv los tiv thaiv deformation los yog tsis ua hauj lwm nyob rau hauv lub zog sab nraud (static loads) yog hu ua lub zog. Qhov muaj peev xwm tiv thaiv sab nraud ntau dua, lub zog ntau dua, thiab chav tsev ntawm lub zog yog Pa lossis Mpa (N / mm2 lossis MN / m2). Raws li lub zog sib txawv ntawm cov khoom siv, lub zog tau muab faib ua tensile zog, compressive zog, thiab flexural zog.
Plasticity: Lub peev xwm ntawm cov khoom siv mus tas li deformation yam tsis muaj kev puas tsuaj rau sab nraud yog hu ua plasticity. Qhov ntau dua cov yas deformation ntawm cov khoom nyob rau hauv sab nraud rog, qhov zoo dua nws plasticity.
Elasticity: Thaum cov khoom raug deformation nyob rau hauv lub zog sab nraud thiab tseem tuaj yeem rov qab mus rau nws lub xeev qub txawm tias tom qab cov rog sab nraud raug tshem tawm, nws yog hu ua elasticity.
Brittleness: Ib yam khoom uas tsis pom qhov tseem ceeb deformation los yog tawg tsis kam nyob rau sab nraud yog hu ua brittle.
Impact toughness: Lub peev xwm ntawm cov khoom siv los tiv thaiv lub zog cuam tshuam yam tsis muaj kev puas tsuaj yog hu ua kev cuam tshuam toughness.
Fracture toughness: Lub peev xwm ntawm cov khoom siv los tiv thaiv kev nthuav tawm ntawm cov kab nrib pleb me me tshwm sim los ntawm ntau yam laj thawj nyob rau sab nraud yog hu ua tawg toughness.
Hardness: Lub peev xwm ntawm cov khoom siv los tiv thaiv cov khoom nyuaj los ntawm kev puas tsuaj thaum nias rau hauv, lossis lwm yam, lub peev xwm ntawm cov khoom siv los tiv thaiv cov yas thiab elastic deformation, hu ua hardness.
