Vim li cas Ua Kev Xeem Flexure? Kev sim flexure ua kom muaj kev ntxhov siab nyob rau sab ntawm lub cev ntawm cov qauv thiab kev ntxhov siab nyob rau sab concave. Qhov no tsim ib cheeb tsam ntawm shear stress nyob rau hauv nruab nrab. Txhawm rau kom ntseeg tau tias thawj qhov tsis ua tiav los ntawm tensile lossis compression stress lub shear stress yuav tsum raug txo kom tsawg.

Vim li cas peb thiaj ua flexural test?

Kev ntsuas Flexural ntsuas lub zog uas yuav tsum tau khoov ib kab ntawm cov khoom yas thiab txiav txim siab qhov tsis kam mus rau flexing lossis tawv ntawm cov khoom. Flex modulus yog qhov qhia txog ntau npaum li cas cov khoom tuaj yeem hloov ua ntej deformation mus tas li.

Vim li cas lub zog flexural tseem ceeb?

High flexural lub zog yog qhov tseem ceeb rau kev ntxhov siab-kev kho kom rov zoo, thaum muaj kev kub ntxhov / kev ntxhov siab rau ntawm cov khoom lossis kev kho dua tshiab. Raws li qhov tshwm sim, lub zog flexural kuj txiav txim siab qhov kev qhia uas siv tau.

Kev ntsuas flexural ua li cas?

Kev ntsuas flexure yog qhov pheej yig dua li qhov ntsuas tensile thiab cov txiaj ntsig kev xeem sib txawv me ntsis. Lub khoom yog nteg kab rov tav hla ob lub ntsiab lus ntawm kev sib cuag (kev txhawb nqa qis dua)thiab tom qab ntawd ib lub zog siv rau saum cov khoom los ntawm ib lossis ob lub ntsiab lus ntawm kev sib cuag (sab saum toj thauj khoom) kom txog thaum tus qauv ua tsis tiav.

Vim li cas peb thiaj li siv peb qhov kev ntsuas bending?

Qhov peb taw tes khoov qhov ntsuas (Daim duab 1) yog qhov kev sim classical hauv kev siv tshuab, siv ntsuastus hluas lub modulus ntawm ib cov khoom nyob rau hauv cov duab ntawm ib tug beam. Lub nqaj, ntawm qhov ntev L, so ntawm ob qhov kev txhawb nqa rau menyuam yaus thiab raug rau cov khoom hnyav P ntawm nws qhov chaw.
