Kev deformation tuaj yeem tshwm sim raws li kev sib koom ua ke (tseem hu ua tawg lossis tensile tawg) uas tsis muaj kev hloov pauv tshwm sim raws li qhov tsis sib xws, lossis ua txhaum qhov kev hloov pauv. tshwm sim. 'Shear fracture' yog siv los hais txog qhov hloov pauv me me uas tshwm sim los ntawm qhov pib tsim ntawm pob txha.

Dab tsi ua rau brittle deformation?

Zoo li tib neeg, lub ntiaj teb pob zeb teb rau kev ntxhov siab ntau yam. … Lwm lub sij hawm, lub pob zeb tsis tuaj yeem tiv taus qhov siab thiab yuav tawg, uas yog hu ua brittle deformation. Qhov no tuaj yeem tshwm sim los ntawm tus lej siab, uas yog tus lej ntawm lub sijhawm. Ductile deformation tshwm sim ntawm tus nqi qis dua.

Nyob qhov txhab elastic deformation tshwm sim?

Elastic deformation yog daim ntawv tseem ceeb ntawm deformation ntawm qhov tob tob hauv cov pob zeb thiab lithosphere vim tias qhov kub thiab qhov siab tsis tshua muaj. Txawm li cas los xij lub crust thiab lithosphere kuj nkig thiab thaum muaj kev ntxhov siab loj txaus, tsis ua hauj lwm los ntawm kev tawg lossis kev sib txhuam zawv zawg kuj tshwm sim.

Nyob rau hauv qhov xwm txheej twg koj xav kom muaj kev ntxhov siab ua rau nkig deformation?

Shear stress yog ib hom kev txwv siab. Pob zeb raug cua sov yuavntau dua yuav dhau los ntawm kev deformation tawg thaum ntxhov siab. Qee qhov kev tawm tsam-slip yog qhov loj txaus kom haum rau kev txav ntawm ob daim phiaj tectonic.

Qhov twg nkig vs ductileDeformation tshwm sim?

Brittle deformation: Irreversible strain thaum pob zeb tawg hauv daim teb rau kev ntxhov siab. Txhua yam khoom uas tawg mus rau hauv daim ntawv qhia txog tus cwj pwm nkig. Ductile deformation: thaum cov pob zeb ntws los yog khoov rau hauv cov lus teb rau kev ntxhov siab (xws li av nplaum).
