Qhov sib txawv tseem ceeb ntawm elastic modulus thiab Young's modulus yog tias elastic modulus yog hais txog qhov sib piv ntawm lub zog quab yuam los ntawm ib yam khoom mus rau qhov tshwm sim deformation, whereas Young's modulus yog hais txog kev ntsuas lub peev xwm ntawm cov khoom siv los tiv thaiv kev hloov pauv. nyob rau hauv ntev thaum nws nyob rau hauv lengthwise nro los yog compression.
Elastic modulus tuaj yeem piav qhia raws li chav ntsuas ntawm cov khoom lossis cov khoom tiv thaiv rau deformation elastically raws li kev siv kev ntxhov siab. Young's modulus tuaj yeem piav qhia tias yog cov cuab yeej siv tshuab uas ntsuas qhov tensile lossis compressive nruj ntawm cov khoom thaum lub zog siv ntev.
YElastic Modulus yog dab tsi?
Elastic modulus yog chav ntsuas ntawm ib qho khoom lossis cov khoom tiv thaiv rau deformation elastically raws li kev siv kev ntxhov siab. Qhov no tseem hu ua modulus ntawm elasticity. Nyob rau hauv lwm yam lus, elastic modulus yog txoj kab nqes ntawm nws txoj kev ntxhov siab-strain nkhaus nyob rau hauv lub elastic deformation cheeb tsam. E.g. Cov khoom siv tawv tawv yuav muaj cov qauv elastic dua.
Muaj peb hom elastic moduli: Young's modulus, shear modulus, thiab bulk modulus. Ntawm lawv, Young's modulus nyiam piav txog tensile elasticity los yog nyiam ntawm ib yam khoom rau deform raws ib qho axis thaum tawm tsam quab yuam siv raws li qhov tshwj xeeb axis. Qhov thib ob modulus, shear modulus, piav qhia txog qhov nyiam ntawm ib yam khoom rau shear thaum ua raws li kev tawm tsam. Qhov ntau modulus piav qhia txog qhov ntim elasticity lossis qhov nyiam ntawm ib qho khoom ua rau deformation thaum sib npaug ntawm txhua qhov kev qhia.
Qee zaum, cov qauv ntawm elasticity hu ua elastic tas li, whereas qhov inverse ntau ntawm qhov ntsuas no hu ua elastic modulus. Tsis tas li ntawd, cov kua dej inviscid yog qhov tshwj xeeb vim lawv tsis tuaj yeem txhawb nqa kev ntxhov siab. Qhov no txhais tau hais tias lub shear modulus yog ib txwm xoom.
Yoob tus Modulus yog dab tsi?
Young's modulus yog cov cuab yeej siv tshuab uas ntsuas qhov tensile lossis compressive nruj ntawm cov khoom thaum lub zog siv ntev. Nws tseem hu ua modulus ntawm elasticity vim nws yog ib hom elastic modulus. Qhov kev ntsuas no tuaj yeem ntsuas qhov kev sib raug zoo ntawm tensile/compressive stress thiab axial strain nyob rau hauv linear elastic cheeb tsam ntawm ib yam khoom.
Daim duab 01: Txoj Kev nqes nqes hais txog Young's Modulus
Young's modulus tso cai rau peb suav cov kev hloov pauv ntawm qhov ntev ntawm lub bar ua los ntawm cov khoom siv isotropic elastic nyob rau hauv tensile lossis compressive loads. Piv txwv li, nws tuaj yeem ntsuas ntau npaum li cas cov qauv siv txuas ntxiv hauv qhov nro lossis luv luv hauv compression.
Qhov txawv ntawm Elastic Modulus thiab Young's Modulus yog dab tsi?
Qhov sib txawv tseem ceeb ntawm elastic modulus thiab Young's modulus yog tias elastic modulus yog hais txog qhov piv ntawm lub zog quab yuam los ntawm ib yam khoom mus rau qhov tshwm sim deformation, whereas Young's modulus yog hais txog kev ntsuas ntawm lub peev xwm ntawm cov khoom los tiv thaiv kev hloov pauv. nyob rau hauv ntev thaum nws nyob rau hauv lengthwise nro los yog compression.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm elastic modulus thiab Young's modulus hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Elastic Modulus vs Young's Modulus
Elastic modulus yog chav ntsuas ntawm ib qho khoom lossis cov khoom tiv thaiv rau deformation elastically raws li kev siv kev ntxhov siab. Young's modulus yog cov cuab yeej cuab tam uas ntsuas qhov tensile lossis compressive nruj ntawm cov khoom thaum lub zog siv ntev. Qhov sib txawv tseem ceeb ntawm elastic modulus thiab Young's modulus yog tias elastic modulus yog hais txog qhov sib piv ntawm lub zog quab yuam los ntawm ib yam khoom mus rau qhov tshwm sim deformation, whereas Young's modulus yog hais txog kev ntsuas ntawm lub peev xwm ntawm cov khoom los tiv thaiv kev hloov ntawm qhov ntev thaum nws yog. nyob rau hauv lengthwise nro los yog compression.
