Yield Strength (0.2% offset) vs Load at 0.2% Offset (F)
Formula
## Yield Strength (0.2% Offset Method) Yield strength marks the transition from elastic to plastic deformation. Since many materials do not have a sharp yield point, the 0.2% offset method draws a line parallel to the elastic region, offset by 0.2% strain, and the intersection with the stress-strain curve defines yield. ### Formula **sigma_y = F_yield / A_0** where F_yield is the load at the 0.2% offset intersection and A_0 is the original cross-sectional area.
Esempio Risolto
A 10 mm diameter aluminum specimen yields at 30 kN using the 0.2% offset method.
- 01Area = pi × 5² = 78.54 mm²
- 02sigma_y = 30000 / 78.54 = 382.0 MPa
