Stress strain diagram

A clean 2D engineering stress-strain plot on a white background, with strain on the horizontal axis and stress on the vertical axis. The curve starts at the origin with an initial straight linear elastic segment, passes through a yield point, then enters a curved plastic deformation and strain-hardening region, reaches a peak ultimate strength, and then falls slightly or levels toward fracture. Rendered in simple textbook style with thin black axes, no grid, and a smooth bold curve; include small labeled key marker points along the curve such as O, y, i, u, and f where shown.
