What does the stress-strain curve of mild steel really tell us? 🤔

In this short, we break down the full behavior of mild steel under a tensile test:

📈 Elastic region → linear and reversible
⚠️ Yield point → start of permanent deformation
💪 Ultimate stress → maximum strength
🔻 Necking → localized reduction in area
💥 Fracture → final failure

This curve is fundamental to understanding ductility, strength, and real material behavior.
