Cov yam ntxwv uas cuam tshuam lub zog ntawm lub pob zeb thiab yuav ua li cas nws yuav deform muaj xws li kub , confining siab , pob zeb hom, thiab lub sijhawm.

Cov lus nug tseem yog, dab tsi yog 3 txoj hauv kev uas lub pob zeb tuaj yeem deform?

Thaum twg pob zeb deform lawv hais tias strain. Ib hom kab mob yog qhov hloov pauv loj, zoo li, lossis ntim ntawm cov khoom.

Peb hom kev ntxhov siab sib txawv tshwm sim.

• Tensional stress (los yog extensional stress), uas stretches pob zeb;
• Compressional kev nyuaj siab, uas squeezes pob zeb; thiab.
• Shear stress, uas ua rau slippage thiab txhais lus.

Dab tsi ua rau deformation ntawm pob zeb? Pob zeb Puas Muaj Kev Nyuaj Siab ua rau pob zeb rau deform , meaning the pob zeb hloov qhov loj los yog duab. Shear stress yog thaum pob zeb swb nyob rau hauv ib txoj kab rov tav. Nrog shear stress, lub pob zeb raug rub tawm hauv cov lus qhia sib txawv tab sis ntawm qhov sib txawv.

Raws li txoj cai, ob yam dab tsi uas tuaj yeem cuam tshuam cov khoom ntawm pob zeb?

Ntau khoom kuj yog nyob ntawm cov nplej lossis siv lead ua loj, cov duab, thiab kev ntim khoom, tus nqi thiab kev faib tawm ntawm qhov chaw tsis muaj dab tsi, muaj cov cements ntuj nyob hauv sedimentary. pob zeb , qhov kub thiab txias, thiab hom thiab tus nqi ntawm cov kua dej (piv txwv li, dej, roj av, gases).

Cov pob zeb cuam tshuam li cas los ntawm ntau hom kev ntxhov siab?

Kev nyuaj siab tuaj yeem ua kom txias, compression, nruj , los yog shear. Pob zeb hauv qab kev ntxhov siab tej zaum yuav qhia strain los yog deformation. Deformation tuaj yeem yog elastic lossis yas, lossis pob zeb tuaj yeem tawg. Pob zeb teb rau kev ntxhov siab txawv hauv qab txawv tej yam kev mob.
