The relationship between the stress and strain that a particular material displays is known as that material's stress-strain curve. It is unique for each material and is found by recording the amount of deformation (strain) at distinct intervals of tensile or compressive loading (stress). These curves reveal many of the properties of a material, including the modulus of elasticity (E).
