Hlau teeb duab ntawm kev ntxhov siab vim ob lub compressive ntxhov siab muaj tensile kev ntxhov siab lub xeev piv rau cov xaim xaim hluav taws xob piv rau kev kos duab yas yooj yim dua. Teeb duab deformation rau compressive deformation ntawm tensile deformation rau ob ntawm peb lub xeev tseem ceeb, yas, thiab muaj ntau dua rau kev tsis xws luag thiab kis tau. Cov txheej txheem kos duab ntawm xaim xaim pib qhov kev nyab xeeb ntawm deformation kis muaj ntau yam kev kos duab, yog li feem ntau siv hauv kev tsim cov hlau sib law liag sib law liag kev kub ceev.
