1200-1500MPa
Lub zog dabtsi yog khoov ntawm cov hlau ncej feem ntau yog nruab nrab ntawm 1200-1500MPa. Bending zog yog hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv kev khoov yam tsis muaj kev tawg, thiab yog ib qho tseem ceeb rau kev ntsuam xyuas qhov kev ntxhov siab khoov uas cov khoom tuaj yeem tiv taus. Thaum xaiv cov hlau ncej, nws yog ib qho tsim nyog yuav tau xaiv lub ncej nrog lub zog khoov kom tsim nyog raws li cov kev ntxhov siab hauv qhov kev thov tiag tiag.
Txhais thiab suav txoj kev khoov lub zog
Bending zog yog hais txog lub load rau ib cheeb tsam ib cheeb tsam thaum ib tug load yog siv ntawm ob lub ntsiab lus txhawb nqa ntawm ib tug qauv mus txog rau thaum tus qauv raug puas tsuaj. Cov mis laij lej yog:
[ R=\frac{3F \times L}{2b \times h \times h} ]
Qhov twg, (F) yog qhov tawg, (L) yog qhov dav, (b) yog qhov dav, thiab (h) yog qhov tuab. Feem ntau siv peb-point bending test method.
