These values often need to be determined for any type of cold formation of the material. The flow curve is often used to determine two parameters characteristic of the material, the strain hardening exponent and the coefficient of the strength of the material. True stress-true strain curves are often called flow curves, which represent plastic flow of the material. Thus, the Engineering Stress which is based on the original area decreases beyond the Ultimate Tensile Strength, whereas the True Stress increases, due to the necking or reduction of area that occurs to the specimen cross section. When a ductile material is loaded beyond its Ultimate Tensile Strength, necking occurs and the cross sectional area and applied force both decrease.
