Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm kev siv cov raj plaub fab, cov hlau channel, cov hlau kaum sab xis

Cov txiaj ntsig ntawmlub raj plaub fab
Lub zog compressive siab, lub zog bending zoo, lub zog torsional siab, kev ruaj khov zoo ntawm qhov loj me.
Vuam, kev sib txuas, kev ua tiav yooj yim, zoo plasticity, txias bending, txias dov kev ua tau zoo.
Thaj chaw loj, hlau tsawg dua ib chav tsev thaj chaw, txuag hlau.
Cov prongs nyob ib puag ncig tuaj yeem ua kom lub peev xwm shear ntawm tus tswv cuab zoo dua.

Qhov tsis zoo
Qhov hnyav theoretical loj dua li cov hlau channel, tus nqi siab.
Tsuas yog tsim rau cov qauv uas muaj kev xav tau siab zog.

Cov txiaj ntsig ntawmCov hlau channel
Muaj zog khoov thiab torsional ntau dua, tsim nyog rau cov qauv uas raug kev khoov thiab torsional ntau dua.
Me dua qhov loj ntawm seem, sib dua, txuag hlau.
Kev tiv taus shear zoo, tuaj yeem siv rau cov qauv uas raug rau cov zog shear loj.
Kev siv tshuab ua yooj yim, tus nqi qis.

Qhov tsis zoo
Lub zog compressive qis dua, tsuas yog tsim rau cov qauv uas raug khoov lossis torsion.
Vim yog qhov sib tshuam tsis sib luag, nws yooj yim los tsim cov buckling hauv zos thaum raug kev nyuaj siab.

Cov txiaj ntsig ntawmLub kaum sab xis
Cov duab yooj yim hla, yooj yim rau tsim, pheej yig.
Nws muaj kev tiv thaiv zoo rau kev khoov thiab torsion thiab tsim nyog rau cov qauv uas muaj lub sijhawm khoov thiab torsion loj.
Siv tau los ua ntau yam qauv thav duab thiab braces.

Qhov tsis zoo
Lub zog compressive qis dua, tsuas yog siv rau cov qauv uas raug khoov lossis torsion.
Vim yog qhov sib tshuam tsis sib luag, nws yooj yim los tsim cov buckling hauv zos thaum raug compression.

Cov raj plaub fab, cov raj u channel thiab cov raj kaum sab xis muaj lawv qhov zoo thiab qhov tsis zoo, thiab yuav tsum tau xaiv raws li daim ntawv thov tiag tiag.
Yog tias xav tau kev nyuaj siab loj, lub raj square yog qhov kev xaiv zoo dua.
Yog tias muaj cov quab yuam loj lossis cov torsion, cov channel thiab cov ces kaum yog qhov kev xaiv zoo dua.
Yog tias xav tau kev xav txog tus nqi thiab cov txheej txheem ua tiav, cov hlau channel thiab cov hlau kaum sab xis yog qhov kev xaiv zoo dua.
