Web🕑 Reading time: 1 minute The stress-strain curve describes the behavior of steel bars under loads. It is created by testing steel specimens. A steel specimen is gradually pulled through a testing machine until it breaks, and stress and corresponding strains are recorded. The stresses are then plotted along the vertical axis, and as a […] WebThe ultimate tensile strength is the maximum on the engineering stress-strain curve. This corresponds to the maximum stress sustained by a structure in tension. Ultimate tensile strength is often shortened to “tensile strength” or “the ultimate.”. If this stress is applied and maintained, a fracture will result.
