ultimate load

From O to A the stress is proportional to the strain and A is the proportional limit. At B, elongation begins and the material becomes plastic. The yield point is thus at C, at which point the material begins to strain harden. Point D represents the maximum tensile stress or the ultimate strength. At E the fracture takes place. E is the ultimate load in this case.
