Stress–strain curve

Uncommon card · No. 104786

In engineering and materials science, a stress–strain curve for a material gives the relationship between the applied pressure, known as stress, and amount of deformation, known as strain. It is obtained by gradually applying load to a test object and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength, and the ultimate tensile strength.
