Compression Stress

Compression yog hom kev ntxhov siab uas ua rau cov pob zeb sib tsoo lossis sib tsoo. Nws tsom rau qhov nruab nrab ntawm lub pob zeb thiab ua tau ua rau kab rov tav lossis ntsug orientation. Hauv kab rov tav compression kev nyuaj siab , lub crust ua tau thicken los yog luv

Tom qab ntawd, ib tug kuj yuav nug, hom kev ntxhov siab yog compression?

Kev ntxhov siab yog lub zog siv rau lub pob zeb, uas yuav ua rau deformation . Peb lub ntsiab ntawm kev ntxhov siab mus nrog rau peb hom phaj ciam teb: compression yog ib qho ntawm convergent ciam teb, nruj ntawm divergent ciam teb, thiab txiav ntawm kev hloov ciam teb.

Tsis tas li ntawd, puas yog compressive kev ntxhov siab zoo lossis tsis zoo? Compressive kev nyuaj siab muaj kev ntxhov siab units (force per unit cheeb tsam), feem ntau nrog tsis zoo qhov tseem ceeb los qhia qhov compaction. Txawm li cas los xij, hauv geotechnical engineering, compressive kev nyuaj siab yog sawv cev nrog zoo tus nqi.

Ib sab saum toj no, dab tsi yog qhov piv txwv ntawm lub neej tiag tiag ntawm kev ntxhov siab?

_ _ Ib lub voj voog zoo li Mid-Atlantic Ridge yog tsim thaum ob daim phiaj tectonic rub sib nrug ntawm ib leeg.

Dab tsi yog compressive thiab tensile stress?

Compressive kev nyuaj siab yog qhov opposite ntawm tensile kev nyuaj siab . Ib yam khoom muaj kev paub txog a compressive kev nyuaj siab thaum lub zog squeezing rau ntawm qhov khoom. Qhov sib txawv tseem ceeb ntawm tensile thiab compressive kev nyuaj siab yog tias tensile kev nyuaj siab ua rau elongation whereas compressive kev nyuaj siab ua rau shortening.
