iav yog cov khoom siv tawv thiab nkig.Txawm li cas los xij, tsuav yog nws melted ntawm qhov kub thiab txias sai sai los ntawm qhov me me rau hauv cov iav fiber ntau, cov khoom siv tau yooj yim heev.Ib yam yog iav, yog vim li cas cov iav blocks yog ib qho nyuaj thiab nkig, thaum lub iav fiber ntau yog hloov tau thiab hloov tau?Qhov no tau piav qhia tau zoo los ntawm cov qauv geometric.

Xav txog kev khoov ib tug pas (xav tias tsis muaj kev tawg), thiab qhov sib txawv ntawm tus pas yuav deformed mus rau qhov sib txawv, tshwj xeeb tshaj yog, sab nraud yog stretched, sab hauv yog compressed, thiab qhov loj ntawm lub axis yuav luag tsis hloov.Thaum khoov ntawm tib lub kaum sab xis, lub nplaum nplaum, qhov tsawg dua sab nraud yog stretched thiab tsawg dua sab hauv yog compressed.Nyob rau hauv lwm yam lus, lub thinner, qhov me me ntawm lub zos tensile los yog compressive deformation rau tib degree ntawm dabtsi yog khoov.Txhua yam khoom tuaj yeem ua rau qee qhov kev hloov pauv tas li, txawm tias iav, tab sis cov ntaub ntawv nkig tuaj yeem tiv taus qhov deformation tsawg tshaj li cov ntaub ntawv ductile.Thaum cov iav fiber ntau yog nyias txaus, txawm tias qhov loj ntawm kev khoov tshwm sim, qhov degree ntawm tensile hauv zos lossis compressive deformation yog me me, uas yog nyob rau hauv cov kabmob ntawm cov khoom, yog li nws yuav tsis tawg.
