Kev ntsuam xyuas kev ua tau zoo ntawm cov tshuab yog ib qho tseem ceeb rau kev ntsuas tus cwj pwm ntawm cov neeg kho tshuab (xws li lub zog, hardness, toughness, thiab ductility) ntawm cov cuab yeej siv tshuab thiab nws cov ntaub ntawv nyob rau hauv kev ntxhov siab, tsom xyuas seb lawv puas ua tau raws li cov qauv tsim, kev nyab xeeb, thiab kev ntseeg tau. Nws lub hom phiaj tseem ceeb suav nrog kev txheeb xyuas kev nyab xeeb, kev ua haujlwm kom muaj nuj nqis, thiab kev ua kom zoo dua.
Cov khoom kuaj tseem ceeb muaj xws li kev sim tensile, kev sim compression, kev sim khoov, kev ntsuam xyuas shear, kev ntsuam xyuas cuam tshuam, kev sim hardness, flattening tests, flaring tests, thiab kev sim qaug zog.
Raws li qhov xwm txheej ntawm qhov kev xeem, cov kev ntsuam xyuas tuaj yeem muab faib ua cov kev ntsuas kev ua haujlwm zoo li qub (xws li nro, compression, dabtsi yog khoov, shear, thiab torsion), kev ntsuas kev ua tau zoo (xws li cuam tshuam, qaug zog, thiab kev vibration), thiab kev ntsuas tshwj xeeb (xws li hardness, creep, thiab hnav).
Lub hauv paus ntsiab lus ntawm kev sim yog siv lub nra rau cov qauv siv lub tshuab kuaj thiab ntsuas nws cov lus teb (xws li deformation thiab tawg). Cov cuab yeej ntsuas tseem ceeb suav nrog cov tshuab ntsuas thoob ntiaj teb, cov tshuab ntsuas qhov cuam tshuam, cov ntsuas qhov tawv tawv, thiab cov tshuab ntsuas qaug zog. Ntawm cov no, lub microcomputer- tswj hluav taws xob thoob ntiaj teb kev sim tshuab tau dhau los ua cov khoom siv tseem ceeb hauv cov ntaub ntawv niaj hnub science rau kev ua ntau yam cuab yeej cuab tam thiab kev sim tshwj xeeb. Cov cuab yeej no muaj qhov ua tau zoo, qib siab ntawm automation, thiab muaj peev xwm ua cov ntaub ntawv muaj zog, nrog kev ntsuas qhov tseeb ntawm ± 0.5% lossis siab dua.
