Area under the stress-strain curveUnderstanding Stress-Strain Curves
Key Regions of the Curve:
- Elastic Region: Material follows Hooke's Law (σ = Eε). Deformation is reversible.
- Yield Point: Transition from elastic to plastic behavior at yield strength (σy).
- Plastic Region: Permanent deformation follows Hollomon equation (σ = Kεn).
- Ultimate Tensile Strength: Maximum stress before necking begins.
- Necking Region: Localized deformation leading to failure.
- Fracture Point: Complete material failure at elongation limit.
