High Quality Content by WIKIPEDIA articles! The various definitions of tensile strength are shown in the following stress-strain graph for low-carbon steel: Stress vs. Strain curve typical of structural steel.Metals including steel have a linear stress-strain relationship up to the yield point, as shown in the figure. In some steels the stress falls after the yield point. This is due to the interaction of carbon atoms and dislocations in the stressed steel. Cold worked and alloy steels do not show this effect.

High Quality Content by WIKIPEDIA articles! The various definitions of tensile strength are shown in the following stress-strain graph for low-carbon steel: Stress vs. Strain curve typical of structural steel.Metals including steel have a linear stress-strain relationship up to the yield point, as shown in the figure. In some steels the stress falls after the yield point. This is due to the interaction of carbon atoms and dislocations in the stressed steel. Cold worked and alloy steels do not show this effect. For most metals yield point is not sharply defined. Below the yield strength all deformation is recoverable, and the material will return to its initial shape when the load is removed. This recoverable deformation is known as elastic deformation. For stresses above the yield point the deformation is not recoverable, and the material will not return to its initial shape. This unrecoverable deformation is known as plastic deformation.
