Kev nyuaj siab yog lub zog ua haujlwm ntawm pob zeb hauv ib cheeb tsam. Txhua lub pob zeb tuaj yeem strained. Lim Nws tuaj yeem yog elastic, nkig, los yog ductile. Ductile deformation kuj hu ua yas deformation. Cov qauv hauv geology yog cov yam ntxwv deformation uas tshwm sim los ntawm kev ruaj khov (nkim los yog ductile) mob.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog kev ntxhov siab hauv geology?

Kev nyuaj siab yog lub zog siv rau ib yam khoom. Hauv geology , kev ntxhov siab yog lub zog ib chav tsev uas muab tso rau ntawm ib lub pob zeb. Tension yog hom loj ntawm kev ntxhov siab ntawm divergent phaj ciam teb. Thaum lub zog sib npaug tab sis txav mus rau qhov sib txawv, cov kev ntxhov siab hu ua shear (daim duab 2).

Tom qab ntawd, lo lus nug yog, dab tsi yog strain piav qhia? Lim yog cov lus teb ntawm ib qho system rau kev siv kev ntxhov siab. Thaum cov khoom ntim nrog lub zog, nws ua rau muaj kev ntxhov siab, uas ua rau cov khoom deformation. Engineering mob yog txhais raws li tus nqi ntawm deformation nyob rau hauv cov kev taw qhia ntawm kev siv quab yuam muab faib los ntawm thawj qhov ntev ntawm cov khoom.

Tom qab ntawd, lo lus nug yog, dab tsi yog txhais los ntawm kev ntxhov siab thiab kev nyuaj siab?

Kev nyuaj siab yog lub internal resisting rog ib cheeb tsam tsim nyob rau hauv lub cev tiv thaiv deformation. Nws yog muab los ntawm. f = P / A qhov twg P = load thov thiab thaj tsam ntawm ntu ntu. Thaum mob yog ib qhov dimensionless kom muaj nuj nqis txhais raws li qhov ratio ntawm kev hloov nyob rau hauv dimension mus rau qhov qub dimension.

3 hom kab mob yog dab tsi?

Hauv kev teb rau kev ntxhov siab, pob zeb yuav raug mob peb hom sib txawv - elastic mob , cev mob , los yog tawg. Elastic mob yog thim rov qab.
