Brittleness

Brittleness yog hais txog cov cuab yeej uas cov khoom tsuas yog ua rau me me deformation nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam (xws li tensile, cuam tshuam, thiab lwm yam), uas yog, tawg tsis ua hauj lwm. Nyob rau hauv sib piv rau toughness, tsuas yog ib tug me me elastic deformation tshwm sim ua ntej puas thiab tsis muaj yas deformation tshwm sim. Cov ntaub ntawv brittle muaj qhov tsis zoo rau cov khoom hnyav lossis kev poob siab. Lub brittleness ntawm cov ntaub ntawv hlau feem ntau yog nyob ntawm nws cov muaj pes tsawg leeg thiab cov qauv.
