Tõmbekõver saadakse, rakendades järk-järgult koormust katseteimikule ja mõõtes deformatsiooni, mille tulemusel saadud kõver näitab paljusid materjali omadusi iseloomustavaid suurusi, nagu Youngi moodul, voolavuspiir, ülim tõmbetugevus jne.
Stress-strain curve is obtained by gradually applying load to a test coupon and measuring the deformation. These curve reveal many of the properties of a material, such as the Young's modulus, the yield strength and the ultimate tensile strength.
