Cov lus qhia
Paib lub zog
Tos lub zog yog qhov kev ntxhov siab tshaj plaws uas cov khoom tuaj yeem tiv taus ua ntej nws ua yas. Txog cov ntaub ntawv hlau, tawm lub zog yog ib qho tseem ceeb cov khoom ntiag tug ntawm cov khoom siv ntawm cov khoom hloov pauv los ntawm kev tawm tsam yas.
Ntawm kev ntxhov siab-lim nkhaus, tawm los ntawm lub zog feem ntau sib raug rau ib qho chaw tshwj xeeb ntawm txoj kev nkhaus, cov paib taw tes. Rau ntau cov hlau, cov txiaj ntsig tau tshwm sim yog qhov sib txawv uas zoo li qhov kis tau tus kheej lossis toj siab ntawm txoj kev nkhaus. Txij ntawm no, cov khoom pib kom yauv yooj yim, thiab kev deformation txuas ntxiv txawm tias kev ntxhov siab tsis muaj ntxiv lawm.
Lub zog tensile
Lub zog tensile yog qhov kev ntxhov siab cov khoom siv raug rau thaum lub sijhawm kuaj tensile. Nws yog ib qho khoom siv tseem ceeb ntawm cov khoom ntiag tug ntsuas ntsuas qhov tsis kam mus rau tensile pob txha pob.
Thaum kuaj Tensile ua yeeb yam, cov qauv khoom yog xyab kom ncav tau kom txog thaum nws tawg. Lub zog tensile feem ntau sib raug rau qhov siab tshaj plaws ntawm kev nkhaus siab-strain-strate, qhia txog qhov kev ntxhov siab tshaj plaws uas cov khoom siv tau ua ntej tawg. Thaum lub zog tensile yog mus txog, cov khoom yuav tawg lossis raug rhuav tshem.
