WebAlthough, rubber on loading returns to its original length (zero extension), the stress-strain graph has two branches (generated by loading up stress and unloading stress). The loop formed by the two branches is called … WebThe ultimate tensile strength is the maximum on the engineering stress-strain curve. This corresponds to the maximum stress that can be sustained by a structure in tension. Ultimate tensile strength is often shortened to “tensile strength” or even to “the ultimate.” If this stress is applied and maintained, fracture will result.
