Kev siv zog yog hais txog lub peev xwm los tiv thaiv kev puas tsuaj nyob rau hauv qhov kev txiav txim ntawm static lotus, nrog rau lub zog tensile, siab tsis kam, khoov lub zog, thiab shear zog. Muaj kev sib txuas ntawm cov kev muaj zog no, ntawm qhov uas lub zog tensile feem ntau suav hais tias yog qhov taw qhia lub zog tshaj plaws. Raws li kev cuam tshuam ntawm kev thauj khoom, lub raj square yuav tsum tau tiv thaiv ntau hom kev ncab, compression, khoov, thiab txiav kom nws ruaj khov thiab kav ntev.
(1) Kev tswj hwm square paub txog nws lub zog zoo thiab toughness, zoo nqa ntau hom kev thauj khoom thiab tawv tawv tsis kam ua kom puas. Nws qhov Performance index yog siab thiab muab kev tiv thaiv zoo rau cov khoom.
(2) Lub raj square muaj kev ua haujlwm zoo hauv kev rov ua haujlwm ib puag ncig, thiab tuaj yeem tswj tau lub sijhawm ntev thiab ruaj khov. Lub toughness ntawm cov khoom no ua lub luag haujlwm tseem ceeb hauv kev thauj khoom, thiab muaj lub zog zoo thiab kev ua haujlwm yas. Kev sib xyaw ua ke zoo heev plasticity thiab kev txhawb nqa muaj peev xwm, nws tau dhau los ua ib qho ntawm cov khoom siv rau kev thauj khoom.
(3) Nyob rau hauv kev tsom xam ntawm kev ua haujlwm Performance index ntawm lub raj square, txawm hais tias lub kaum sab xis ntawm Butana (HB), Luo lub kaum sab xis (HRA, HRB, HRC) thiab lub kaum sab xis Victoria (HV) tuaj yeem siv los ntsuas qhov nyuaj thiab qib nyuaj. ntawm cov ntaub ntawv hlau, tab sis qhov tseeb, qhov teeb meem tiag tiag Thaum lub sij hawm tsim khoom, lub kaum sab xis txoj kev tau dav siv rau nws qhov yooj yim thiab siv tau. Txoj kev no yog nias rau hauv cov hlau nto nyob rau hauv ib lub taub hau geometrical, thiab lub kaum sab xis tus nqi yog txiav txim siab raws li qib ntawm crushed.
(4) Nyob rau hauv kev tsom xam ntawm kev ua haujlwm Performance index ntawm lub raj square, lub kaum sab xis yas hais txog lub peev xwm mus tas li deformed tab sis tsis tawg thaum cov khoom yuav tsum them. Qhov no feature guarantees nws zoo heev load-bearing kev ua tau zoo.
(5) Kev ua haujlwm Performance index ntawm lub raj square yog manifested nyob rau hauv nws zoo heev plasticity thiab txhua yam khoom. Nws muaj lub zog siab thiab muaj kev cuam tshuam zoo thiab tsim nyog rau ntau yam kev txhawb nqa thiab nqa cov haujlwm.
