Key Insights:
- Linear Elastic Region:Stress is proportional to strain (Hooke's Law). Slope is Young's Modulus ().
- Yield Point: Material begins to deform plastically.
- Strain Hardening: Stress increases with strain due to dislocation movements.
- Necking: Cross-sectional area decreases significantly before fracture.
- Ductile Failure: Significant deformation before failure.
