Mechanics of Materials-Steel - Civil Engineering

The strain hardening of the stress-strain curve begins at a strain of approximately 12 times the strain at yield. At that stage, additional stress is required to further extend the material until a maximum stress is reached, after which the stress decreases with increasing the strain, and then fracture occurs.
